Description solarflame 2024-06-20 12:54:26 UTC
SUMMARY
Whenever I try to use a GTK app installed from Flatpak on a wayland session, the window freezes after a second, renders the app unusable, and requires terminating the process to close the window, I have tried with Bottles, Trayscale, and Flatseal, all of them have the same result. They were working just fine before the update to Plasma 6.1

STEPS TO REPRODUCE
1. Install an app built with GTK from Flatpak
2. Launch the app

OBSERVED RESULT
The app window completely freezes and goes into the (Not responding) state

EXPECTED RESULT
The app works normally

I also have this issue. I don't know if it's the cause, but I also happen to be using the 555 proprietary drivers, although on a 1080 Ti.

I also noticed that in a Wayland session, the proprietary driver isn't loaded correctly (I'm not too familiar with Linux graphics pipeline, so "isn't loaded correctly" is my best guess), and it falls back to using llvmpipe instead, but everything works fine on X11.
