Model and tiles flashing when render tow Viewer

CesiumJS
1

Hello, everyone,
I want to make some data visualization comparisons, so I created two scenes (two viewers) and added data to each. After that, the models or tiles in one of the scenes occasionally flash. I don’t know why this is happening.

After testing, I found that versions prior to 1.120 do not have this issue.

Here is a Sandcastle demo

Thanks to the community.

Hi @WShihan ,
Thanks for your post and for using CesiumJS.

I think I am having trouble identifying the exact behavior you described. Is there a particular trigger to the flashes you are seeing? Could you possibly provide a screen capture?

Thanks and hope we can help you get the issues sorted out.

Best,
Luke

Thanks for resposnse, Luke,
No particular trigger.The sandcastle demo runs properly on some computers without flashing, while on others, it does. I shared the demo with my colleague, and he did not see any flashing , which is the same as yours.Is this issue related to hardware?

Here are some screen captures from my computer.

If I zoom in closer to the 3DTiles model, the scene flashes faster.
