Hi,
Flatpaks on my system don’t render well, when they use OpenGL.
Here is a comparison with Krita (This is not about Krita, I want to use a different app which is not available for TW and can currently not be compiled on OBS due to some other library broken):

Switching off the compositor does not make a difference.
Any ideas?
