[Summary]
Firefox on Ubuntu 20.04 (99.0build2-0ubuntu0.20.04.2) window could be glitched with laptops with Intel + NVIDIA GPU, and prime-select set to intel.
Either setting gfx.x11-egl-force-disabled to true in about:config, or setting prime-select to on-demand or nvidia, makes the issue unreproducible.
Note that through nvidia-settings GUI, prime-select cannot be set to intel.
Reproducibility: 1/8
[Reproduce Steps]
1. Run `sudo prime-select intel` in Terminal then reboot
2. Open Firefox window
3. Close Firefox window
4. Repeat until window is glitched (usually Firefox being transparent except the borders of the window)
[Results]
Expected: Firefox should not have its window glitched
Actual: Firefox is glitched with window being transparent but the border, and every window on top of it draws on the Firefox window. Video attached.
