This is propably because app does not support fractional scaling. Some apps that does not support fractional scaling will either not be scaled (rendered at native display resolution), or scaled by system (will look blurry because window resolution does not match display resolution).
I dont know, maybe its some kind of mandela effect i got, because i do need to update flatpak after system update. Maybe i just didnt update flatpak and didnt noticed everything not working until hours later, because lightweight apps didnt run as slow or had graphics bugs.
Its org.freedesktop.Platform.GL.nvidia
I dont have an auto update enabled on my system, and i always reboot system after update. For flatpak specifically, when i hear people complaining about me streaming the black screen, i just update flatpak nvidia package, and dont even need to restart zoom to be able to start streaming again. And as i said, it realy does happen suddenly. I can stream video normally, but few minutes later, while still in meeting, i start streaming again and it shows black screen, while i did absolutely nothing.
Really weird stuff.
I dont need any professional tools for my editing needs. I usually need something that can do basic editing and do it good. Krita is just simpler to use for my use cases than gimp.
While krita is primarily a drawing app, i like it more for general image editing than gimp.
Dont buy at all if it is region restricted
