Description

**Describe the bug**
Under the ANGLE_D3D11 backend in Windows Chrome, the official demo displays random flickering noise. This appears to be a graphical glitch that occurs at irregular intervals.

**To Reproduce**
Steps to reproduce the behavior:
1. Set the backend to ANGLE_D3D11(by default).
2. Open the official demo on Chrome in Windows. https://google.github.io/filament/webgl/suzanne.html
3. Observe the screen for flickering noise.

**Expected behavior**
The demo should run smoothly without any flickering or noise. The graphics should be clear and steady.

**Additional context**
This issue seems to occur randomly and does not appear to be tied to any specific actions or inputs within the demo. Sometimes it can be observed upon refreshing the page, or when resizing the window. Once it starts flickering, resizing the window might potentially restore it to normal.
