Issac Sim is flickering and blinking

Omniverse Isaac Sim

So I am new to issac SIM and I was trying to use the lidar and camera on issac sim on carter_v1 to connect to ros2 foxy. I am using issac sim 4.2.0 and the lidar works fine but when I create the action graph for the camera image_raw, the flickering starts. whats crazy is that after this, I used the carter_nova robot and then the camera action graph was fine but the lidar action graph gave this issue. I have no idea what is happening. I am using two gpu but I already tried going to

apps/omni.isaac.sim.python.kit
and at the very bottom adding

[settings]
rendergraph.mgpu.backend = “copyQueue”

does not work.

Please check if information in Isaac SIM 4.2.0 version, RTX Lidar Sensor has a significant bug that prevents it from functioning properly - #10 by Julie_A is helpful for your problem.

it suggests using standalone and then disable multi-GPU. But I want to use the standard mode with multi GPUs as I have two GPUs and also I want ros2 bridge to foxy. the issac sim removes the ros2 nodes and bridge when I run in standalone mode…

Please try the upcoming release. Note that ROS2 Foxy support is deprecated even in the current version, Isaac Sim 4.2.0.

v4.5.0 does not have the blinking issue with ros2 humble. thanks
