Describe the issue
Hi, I have an issue with some OpenGL applications and the same issue is present when i upgrade Mesa with Kisak or Oibaf PPA with their latest version. First the applications :
- PCSX2 (OpenGL only), the renderer has some graphics artefacts (squares with colors). Renderer in Software mode or OpenGL does the same thing.
- KDEnlive, Shotcut shows exactly the same artefacts.
- Dolphin, this application can do Vulkan renderer and OpenGL renderer. Renderer in OpenGL does the same artefacts.
-> Seems to be a QT rendering problem in OpenGL 4.6 programs (most of them are Flatpak in Mesa 20.0.8), and repositories applications (deb) without QT in Mesa 20.1.4
No problem with 0AD game (OpenGL)
So, i've upgrade with Kisak or Oibaf PPA's (Mesa (20.1.4)) (tested both after uninstall them, ppa:purge). Same artefacts occurs with Google Chrome, Vivaldi Web Browser, Firefox.
Regression
Upgrade with latest Mesa available in PPA (20.1.4)

[EDIT]
- Correction with Kisac name in Kisak
- A newer kernel (5.7.11) don't resolve PCSX2 artefacts with no upgrade of Mesa.
- Upgrade of Mesa (20.1.4) with Kisak PPA don't resolve the problem.
- Kernel 5.8 don't resolve the problem.

- Report QT problems
- Screenshot of Firefox 79.0 with latest Mesa (Kisak PPA)
