Description of problem:

When running applications that uses 3d accelerated rendering, the rendered apps are unusable because the app contents are corrupted (see screenshots).

It is always reproducible with 3d accelerated apps like Blue Archive and Rush Rally 3.

Steps to Reproduce:
1. Open the waydroid overview.
2. Launch one of the listed applications.
3.1 For Blue Archive, launching it will show a black or translucent window, rendering the app unusable.

I found a workaround for Rush Rally 3 by limiting the Framerate to 60. This fixed the rendering issues. But this is just a workaround as only very few applications offer this option and waydroid does not offer global frame limiting options. It could be an AMD specific issue as this seems similar to this reports:
