-GPU Info and selection
-**********************
-
-FAQ
-===
-
-1. Do I need a GPU?
-
-Technically no, you can perform limited software rendering on linux using lavapipe (see drivers link below). However
-``fastplotlib`` is intentionally built for realtime rendering using the latest GPU technologies, so we strongly
-recommend that you use a GPU.
-
-2. My kernel keeps crashing.
-
-This can happen under the following circumstances:
-
-- You have ran out of GPU VRAM.
-- Driver issues (see next section).
-
-If you aren't able to solve it please post an issue on GitHub. :)
-
-3. Nothing renders or rendering is weird, or I see graphical artifacts.
-
-- Probably driver issues (see next section).
-
-Drivers
-=======
-
-See the README: https://github.com/fastplotlib/fastplotlib?tab=readme-ov-file#graphics-drivers
-
-If you notice weird graphic artifacts, things not rendering, or other glitches try updating to the latest stable
-drivers.
-
-GPU Info
-========
-
-View available adapters
------------------------
-
-You can get a summary of all adapters that are available to ``WGPU`` like this::
-
-    import fastplotlib as fpl
-
-    adapters = fpl.enumerate_adapters()
-
-    for a in adapters:
-        print(a.summary)
-
-For example, on a Thinkpad AMD laptop with a dedicated nvidia GPU this returns::
-
-    AMD Radeon Graphics (RADV REMBRANDT) (IntegratedGPU) on Vulkan
-    NVIDIA T1200 Laptop GPU (DiscreteGPU) on Vulkan
-    llvmpipe (LLVM 15.0.6, 256 bits) (CPU) on Vulkan
-    AMD Radeon Graphics (rembrandt, LLVM 15.0.6, DRM 3.52, 6.4.0-0.deb12.2-amd64) (Unknown) on OpenGL
-
-In jupyter all the available adapters are also listed when ``fastplotlib`` is imported.
-
-You can get more detailed info on each adapter like this::
-
-    import pprint
-    for a in fpl.enumerate_adapters():
-        pprint.pprint(a.info)
-
-General description of the fields:
-    * vendor: GPU manufacturer
-    * device: specific GPU model
-    * description: GPU driver version
-    * adapter_type: indicates whether this is a discrete GPU, integrated GPU, or software rendering adapter (CPU)
-    * backend_type: one of "Vulkan", "Metal", or "D3D12"
-
-For more information on the fields see: https://gpuweb.github.io/gpuweb/#gpuadapterinfo
-
-Adapter currently in use
-------------------------
-
-If you want to know the adapter that a figure is using you can check the adapter on the renderer::
-
-    # for example if we make a plot
-    fig = fpl.Figure()
-    fig[0, 0].add_image(np.random.rand(100, 100))
-    fig.show()
-
-    # GPU that is currently in use by the renderer
-    print(fig.renderer.device.adapter.summary)
-
-
-Diagnostic info
----------------
-
-After creating a figure you can view WGPU diagnostic info like this::
-
-    fpl.print_wgpu_report()
-
-
-Example output::

-Select GPU (adapter)
-====================
-
-You can select an adapter by passing one of the ``wgpu.GPUAdapter`` instances returned by ``fpl.enumerate_adapters()``
-to ``fpl.select_adapter()``::
-
-    # get info or summary of all adapters to pick an adapter
-    import pprint
-    for a in fpl.enumerate_adapters():
-        pprint.pprint(a.info)
-
-    # example, pick adapter at index 2
-    chosen_gpu = fpl.enumerate_adapters()[2]
-    fpl.select_adapter(chosen_gpu)
-
-**You must select an adapter before creating a** ``Figure`` **, otherwise the default adapter will be selected. Once a**
-``Figure`` **is created the adapter cannot be changed.**
-
-Note that using this function reduces the portability of your code, because
-it's highly specific for your current machine/environment.
-
-The order of the adapters returned by ``wgpu.gpu.enumerate_adapters()`` is
-such that Vulkan adapters go first, then Metal, then D3D12, then OpenGL.
-Within each category, the order as provided by the particular backend is
-maintained. Note that the same device may be present via multiple backends
-(e.g. vulkan/opengl).
-
-We cannot make guarantees about whether the order of the adapters matches
-the order as reported by e.g. ``nvidia-smi``. We have found that on a Linux
-multi-gpu cluster, the order does match, but we cannot promise that this is
-always the case. If you want to make sure, do some testing by allocating big
-buffers and checking memory usage using ``nvidia-smi``
-
-Example to allocate and check GPU mem usage::
-
-    import subprocess
-
-    import wgpu
-    import torch
-
-    def allocate_gpu_mem_with_wgpu(idx):
-        a = wgpu.gpu.enumerate_adapters()[idx]
-        d = a.request_device()
-        b = d.create_buffer(size=10*2**20, usage=wgpu.BufferUsage.COPY_DST)
-        return b
-
-    def allocate_gpu_mem_with_torch(idx):
-        d = torch.device(f"cuda:{idx}")
-        return torch.ones([2000, 10], dtype=torch.float32, device=d)
-
-    def show_mem_usage():
-        print(subprocess.run(["nvidia-smi"]))
-
-See https://github.com/pygfx/wgpu-py/issues/482 for more details.

+GPU Info and selection
+**********************
+
+FAQ
+===
+
+1. Do I need a GPU?
+
+Technically no, you can perform limited software rendering on linux using lavapipe (see drivers link below). However
+``fastplotlib`` is intentionally built for realtime rendering using the latest GPU technologies, so we strongly
+recommend that you use a GPU.
+
+2. My kernel keeps crashing.
+
+This can happen under the following circumstances:
+
+- You have ran out of GPU VRAM.
+- Driver issues (see next section).
+
+If you aren't able to solve it please post an issue on GitHub. :)
+
+3. Nothing renders or rendering is weird, or I see graphical artifacts.
+
+- Probably driver issues (see next section).
+
+Drivers
+=======
+
+See the README: https://github.com/fastplotlib/fastplotlib?tab=readme-ov-file#graphics-drivers
+
+If you notice weird graphic artifacts, things not rendering, or other glitches try updating to the latest stable
+drivers.
+
+GPU Info
+========
+
+View available adapters
+-----------------------
+
+You can get a summary of all adapters that are available to ``WGPU`` like this::
+
+    import fastplotlib as fpl
+
+    adapters = fpl.enumerate_adapters()
+
+    for a in adapters:
+        print(a.summary)
+
+For example, on a Thinkpad AMD laptop with a dedicated nvidia GPU this returns::
+
+    AMD Radeon Graphics (RADV REMBRANDT) (IntegratedGPU) on Vulkan
+    NVIDIA T1200 Laptop GPU (DiscreteGPU) on Vulkan
+    llvmpipe (LLVM 15.0.6, 256 bits) (CPU) on Vulkan
+    AMD Radeon Graphics (rembrandt, LLVM 15.0.6, DRM 3.52, 6.4.0-0.deb12.2-amd64) (Unknown) on OpenGL
+
+In jupyter all the available adapters are also listed when ``fastplotlib`` is imported.
+
+You can get more detailed info on each adapter like this::
+
+    import pprint
+    for a in fpl.enumerate_adapters():
+        pprint.pprint(a.info)
+
+General description of the fields:
+    * vendor: GPU manufacturer
+    * device: specific GPU model
+    * description: GPU driver version
+    * adapter_type: indicates whether this is a discrete GPU, integrated GPU, or software rendering adapter (CPU)
+    * backend_type: one of "Vulkan", "Metal", or "D3D12"
+
+For more information on the fields see: https://gpuweb.github.io/gpuweb/#gpuadapterinfo
+
+Adapter currently in use
+------------------------
+
+If you want to know the adapter that a figure is using you can check the adapter on the renderer::
+
+    # for example if we make a plot
+    fig = fpl.Figure()
+    fig[0, 0].add_image(np.random.rand(100, 100))
+    fig.show()
+
+    # GPU that is currently in use by the renderer
+    print(fig.renderer.device.adapter.summary)
+
+
+Diagnostic info
+---------------
+
+After creating a figure you can view WGPU diagnostic info like this::
+
+    fpl.print_wgpu_report()
+
+
+Example output::

+Select GPU (adapter)
+====================
+
+You can select an adapter by passing one of the ``wgpu.GPUAdapter`` instances returned by ``fpl.enumerate_adapters()``
+to ``fpl.select_adapter()``::
+
+    # get info or summary of all adapters to pick an adapter
+    import pprint
+    for a in fpl.enumerate_adapters():
+        pprint.pprint(a.info)
+
+    # example, pick adapter at index 2
+    chosen_gpu = fpl.enumerate_adapters()[2]
+    fpl.select_adapter(chosen_gpu)
+
+**You must select an adapter before creating a** ``Figure`` **, otherwise the default adapter will be selected. Once a**
+``Figure`` **is created the adapter cannot be changed.**
+
+Note that using this function reduces the portability of your code, because
+it's highly specific for your current machine/environment.
+
+The order of the adapters returned by ``wgpu.gpu.enumerate_adapters()`` is
+such that Vulkan adapters go first, then Metal, then D3D12, then OpenGL.
+Within each category, the order as provided by the particular backend is
+maintained. Note that the same device may be present via multiple backends
+(e.g. vulkan/opengl).
+
+We cannot make guarantees about whether the order of the adapters matches
+the order as reported by e.g. ``nvidia-smi``. We have found that on a Linux
+multi-gpu cluster, the order does match, but we cannot promise that this is
+always the case. If you want to make sure, do some testing by allocating big
+buffers and checking memory usage using ``nvidia-smi``
+
+Example to allocate and check GPU mem usage::
+
+    import subprocess
+
+    import wgpu
+    import torch
+
+    def allocate_gpu_mem_with_wgpu(idx):
+        a = wgpu.gpu.enumerate_adapters()[idx]
+        d = a.request_device()
+        b = d.create_buffer(size=10*2**20, usage=wgpu.BufferUsage.COPY_DST)
+        return b
+
+    def allocate_gpu_mem_with_torch(idx):
+        d = torch.device(f"cuda:{idx}")
+        return torch.ones([2000, 10], dtype=torch.float32, device=d)
+
+    def show_mem_usage():
+        print(subprocess.run(["nvidia-smi"]))
+
+See https://github.com/pygfx/wgpu-py/issues/482 for more details.

-GPU Info and selection
-**********************
-
-FAQ
-===
-
-1. Do I need a GPU?
-
-Technically no, you can perform limited software rendering on linux using lavapipe (see drivers link below). However
-``fastplotlib`` is intentionally built for realtime rendering using the latest GPU technologies, so we strongly
-recommend that you use a GPU.
-
-2. My kernel keeps crashing.
-
-This can happen under the following circumstances:
-
-- You have ran out of GPU VRAM.
-- Driver issues (see next section).
-
-If you aren't able to solve it please post an issue on GitHub. :)
-
-3. Nothing renders or rendering is weird, or I see graphical artifacts.
-
-- Probably driver issues (see next section).
-
-Drivers
-=======
-
-See the README: https://github.com/fastplotlib/fastplotlib?tab=readme-ov-file#graphics-drivers
-
-If you notice weird graphic artifacts, things not rendering, or other glitches try updating to the latest stable
-drivers.
-
-GPU Info
-========
-
-View available adapters
------------------------
-
-You can get a summary of all adapters that are available to ``WGPU`` like this::
-
-    import fastplotlib as fpl
-
-    adapters = fpl.enumerate_adapters()
-
-    for a in adapters:
-        print(a.summary)
-
-For example, on a Thinkpad AMD laptop with a dedicated nvidia GPU this returns::
-
-    AMD Radeon Graphics (RADV REMBRANDT) (IntegratedGPU) on Vulkan
-    NVIDIA T1200 Laptop GPU (DiscreteGPU) on Vulkan
-    llvmpipe (LLVM 15.0.6, 256 bits) (CPU) on Vulkan
-    AMD Radeon Graphics (rembrandt, LLVM 15.0.6, DRM 3.52, 6.4.0-0.deb12.2-amd64) (Unknown) on OpenGL
-
-In jupyter all the available adapters are also listed when ``fastplotlib`` is imported.
-
-You can get more detailed info on each adapter like this::
-
-    import pprint
-    for a in fpl.enumerate_adapters():
-        pprint.pprint(a.info)
-
-General description of the fields:
-    * vendor: GPU manufacturer
-    * device: specific GPU model
-    * description: GPU driver version
-    * adapter_type: indicates whether this is a discrete GPU, integrated GPU, or software rendering adapter (CPU)
-    * backend_type: one of "Vulkan", "Metal", or "D3D12"
-
-For more information on the fields see: https://gpuweb.github.io/gpuweb/#gpuadapterinfo
-
-Adapter currently in use
-------------------------
-
-If you want to know the adapter that a figure is using you can check the adapter on the renderer::
-
-    # for example if we make a plot
-    fig = fpl.Figure()
-    fig[0, 0].add_image(np.random.rand(100, 100))
-    fig.show()
-
-    # GPU that is currently in use by the renderer
-    print(fig.renderer.device.adapter.summary)
-
-
-Diagnostic info
----------------
-
-After creating a figure you can view WGPU diagnostic info like this::
-
-    fpl.print_wgpu_report()
-
-
-Example output::

-Select GPU (adapter)
-====================
-
-You can select an adapter by passing one of the ``wgpu.GPUAdapter`` instances returned by ``fpl.enumerate_adapters()``
-to ``fpl.select_adapter()``::
-
-    # get info or summary of all adapters to pick an adapter
-    import pprint
-    for a in fpl.enumerate_adapters():
-        pprint.pprint(a.info)
-
-    # example, pick adapter at index 2
-    chosen_gpu = fpl.enumerate_adapters()[2]
-    fpl.select_adapter(chosen_gpu)
-
-**You must select an adapter before creating a** ``Figure`` **, otherwise the default adapter will be selected. Once a**
-``Figure`` **is created the adapter cannot be changed.**
-
-Note that using this function reduces the portability of your code, because
-it's highly specific for your current machine/environment.
-
-The order of the adapters returned by ``wgpu.gpu.enumerate_adapters()`` is
-such that Vulkan adapters go first, then Metal, then D3D12, then OpenGL.
-Within each category, the order as provided by the particular backend is
-maintained. Note that the same device may be present via multiple backends
-(e.g. vulkan/opengl).
-
-We cannot make guarantees about whether the order of the adapters matches
-the order as reported by e.g. ``nvidia-smi``. We have found that on a Linux
-multi-gpu cluster, the order does match, but we cannot promise that this is
-always the case. If you want to make sure, do some testing by allocating big
-buffers and checking memory usage using ``nvidia-smi``
-
-Example to allocate and check GPU mem usage::
-
-    import subprocess
-
-    import wgpu
-    import torch
-
-    def allocate_gpu_mem_with_wgpu(idx):
-        a = wgpu.gpu.enumerate_adapters()[idx]
-        d = a.request_device()
-        b = d.create_buffer(size=10*2**20, usage=wgpu.BufferUsage.COPY_DST)
-        return b
-
-    def allocate_gpu_mem_with_torch(idx):
-        d = torch.device(f"cuda:{idx}")
-        return torch.ones([2000, 10], dtype=torch.float32, device=d)
-
-    def show_mem_usage():
-        print(subprocess.run(["nvidia-smi"]))
-
-See https://github.com/pygfx/wgpu-py/issues/482 for more details.

+If you aren't able to solve it please post an issue on GitHub. :)
+
+3. Nothing renders or rendering is weird, or I see graphical artifacts.
+
+- Probably driver issues (see next section).
+
+Drivers
+=======
+
+See the README: https://github.com/fastplotlib/fastplotlib?tab=readme-ov-file#graphics-drivers
+
+If you notice weird graphic artifacts, things not rendering, or other glitches try updating to the latest stable
+drivers.
+
+GPU Info
+========
+
+View available adapters
+-----------------------
+
+You can get a summary of all adapters that are available to ``WGPU`` like this::
+
+    import fastplotlib as fpl
+
+    adapters = fpl.enumerate_adapters()
+
+    for a in adapters:
+        print(a.summary)
+
+For example, on a Thinkpad AMD laptop with a dedicated nvidia GPU this returns::
+
+    AMD Radeon Graphics (RADV REMBRANDT) (IntegratedGPU) on Vulkan
+    NVIDIA T1200 Laptop GPU (DiscreteGPU) on Vulkan
+    llvmpipe (LLVM 15.0.6, 256 bits) (CPU) on Vulkan
+    AMD Radeon Graphics (rembrandt, LLVM 15.0.6, DRM 3.52, 6.4.0-0.deb12.2-amd64) (Unknown) on OpenGL
+
+In jupyter all the available adapters are also listed when ``fastplotlib`` is imported.
+
+You can get more detailed info on each adapter like this::
+
+    import pprint
+    for a in fpl.enumerate_adapters():
+        pprint.pprint(a.info)
+
+General description of the fields:
+    * vendor: GPU manufacturer
+    * device: specific GPU model
+    * description: GPU driver version
+    * adapter_type: indicates whether this is a discrete GPU, integrated GPU, or software rendering adapter (CPU)
+    * backend_type: one of "Vulkan", "Metal", or "D3D12"
+
+For more information on the fields see: https://gpuweb.github.io/gpuweb/#gpuadapterinfo
+
+Adapter currently in use
+------------------------
+
+If you want to know the adapter that a figure is using you can check the adapter on the renderer::
+
+    # for example if we make a plot
+    fig = fpl.Figure()
+    fig[0, 0].add_image(np.random.rand(100, 100))
+    fig.show()
+
+    # GPU that is currently in use by the renderer
+    print(fig.renderer.device.adapter.summary)
+
+
+Diagnostic info
+---------------
+
+After creating a figure you can view WGPU diagnostic info like this::
+
+    fpl.print_wgpu_report()
+

+Select GPU (adapter)
+====================
+
+You can select an adapter by passing one of the ``wgpu.GPUAdapter`` instances returned by ``fpl.enumerate_adapters()``
+to ``fpl.select_adapter()``::
+
+    # get info or summary of all adapters to pick an adapter
+    import pprint
+    for a in fpl.enumerate_adapters():
+        pprint.pprint(a.info)
+
+    # example, pick adapter at index 2
+    chosen_gpu = fpl.enumerate_adapters()[2]
+    fpl.select_adapter(chosen_gpu)
+
+**You must select an adapter before creating a** ``Figure`` **, otherwise the default adapter will be selected. Once a**
+``Figure`` **is created the adapter cannot be changed.**
+
+Note that using this function reduces the portability of your code, because
+it's highly specific for your current machine/environment.
+
+The order of the adapters returned by ``wgpu.gpu.enumerate_adapters()`` is
+such that Vulkan adapters go first, then Metal, then D3D12, then OpenGL.
+Within each category, the order as provided by the particular backend is
+maintained. Note that the same device may be present via multiple backends
+(e.g. vulkan/opengl).
+
+We cannot make guarantees about whether the order of the adapters matches
+the order as reported by e.g. ``nvidia-smi``. We have found that on a Linux
+multi-gpu cluster, the order does match, but we cannot promise that this is
+always the case. If you want to make sure, do some testing by allocating big
+buffers and checking memory usage using ``nvidia-smi``
+
+Example to allocate and check GPU mem usage::
+
+    import subprocess
+
+    import wgpu
+    import torch
+
+    def allocate_gpu_mem_with_wgpu(idx):
+        a = wgpu.gpu.enumerate_adapters()[idx]
+        d = a.request_device()
+        b = d.create_buffer(size=10*2**20, usage=wgpu.BufferUsage.COPY_DST)
+        return b
+
+    def allocate_gpu_mem_with_torch(idx):
+        d = torch.device(f"cuda:{idx}")
+        return torch.ones([2000, 10], dtype=torch.float32, device=d)
+
+    def show_mem_usage():
+        print(subprocess.run(["nvidia-smi"]))
+
+See https://github.com/pygfx/wgpu-py/issues/482 for more details.
