Cesium MultiView flickers on Windows 11

The sandcastle demonstration along with a personal project flickr badly but only on Windows 11. Tried Edge/Firefox/Chrome - all show same behaviour.

To reproduce - Open Sandcastle demo:

Wait a moment - move one camera and both start to flicker.

Hi @Shaggy, welcome to the community!

I am not able to reproduce on my system: Chrome on Windows 11, NVIDIA GeForce RTX 4070.

Can you give us a little more info about your system? What GPU are you running?

Sorry for late reply. Ran on multiple boxes.

Dell Inspiron beefy box worked until upgrade to win 11.
Just running the demo this is what I see. I’ll try to add specs.

I’m developing multi viewers application also suffering the trouble.
Same issue when I uses cesiumjs 1.121 on win11 with intel core i7 14700 (UHD 770 integrated GPU).
I tryed to upgrade cesiumjs to 1.131 have same problem.

Thanks @fefefesfes for your report and input. Which browsers are you seeing this issue in? The original poster said they saw the issue across Edge/Firefox/Chrome, are you are seeing the same?

@Shaggy it would be helpful to know which GPU you are using as we try to track this down.

Thanks and I hope we can make progress on this. I can open open an issue in the Cesium GitHub repo but I’ll wait to see if we can first gather more information here on this thread.

Thanks,
Luke
