I created window with 4 ViewportWidgets each streaming a camera from the scene.
Even though I provide an exact prim path to the camera that I want the viewport to, it randomly shows other cameras, and then sometimes even crashes Isaac Sim.
Strangely, it seems the viewports stabilize if your mouse cursor is over one of the viewport widgets.
I don’t understand why mousing over the camera would have any effect on which camera is rendered, or the performance.
Thank you for reporting this issue with the ViewportWidget streams in Isaac Sim. It appears you’re experiencing some instability and unexpected behavior with camera rendering in multiple viewports.
I would strongly recommend upgrading to the latest version of Isaac Sim, which is currently version 4.2.0.

Yes, I would like to use the latest version. I tried to upgrade and had other problem so reverted back to 4.0.0 until the installation and libraries issues are resolved.
