os: ubuntu 22.04 x86-64
gpu: l40s x3
example: april tag sample scene

I ran the Isaac Sim example according to the instructions in the April tag.
When it is configured with one GPU, the example can be run without any problems, but when testing with a multi-GPU configuration, the screen flickers or does not display when in play mode.
Since other Isaac Ros examples are not rendered in the same way, this part is problematic. How can I render the Isaac Ros example without any problems in a multi-GPU?
