I have an nvidia gpu, and run some apps through flatpak. And there is weird problem of gpu acceleration suddenly just stops working in flatpak apps.
Normally when i for example run zoom, i can stream my screen no problem, blender gets full performace from gpu. But if run these programs some time later, zoom just shows black screen, and blender lags so much.
In between this time, i did not do anything to installed packages. I did not do a system update, i did not update flatpak packages. Everything should have been working as it worked earlier but it doesnt.
I found out that in between that time, new nvidia driver version is released on flathub, and updating nvidia driver package specifically, fixes gpu acceleration in flatpak apps. But now i have a question, why does already installed driver suddelnly stops working, until i update it?
Had that problem recently, apparently the (nvidia) gpu driver version of the system and the one within the flatpak need to be exactly the same. Ran a flatpak update and it worked again.
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.
