Description Elias 2024-07-21 13:25:19 UTC

SUMMARY
The Krita UI appears to run very slowly. Every menu interaction, tool change, and even simply clicking outside of the canvas causes a 5-10 second delay in the desired action. When drawing in canvas and not using the rest of the UI, everything is fine, so this is not a GL problem. Uninstalling, rebooting, reinstalling does not fix it. Setting all setting back to default does not fix it.

STEPS TO REPRODUCE
1. Start up Krita and open file.
2. Do anything involving the UI - At ALL
3. Attempt to work.

OBSERVED RESULT
A long delay in UI responsiveness.

EXPECTED RESULT
A normal, reasonably snappy response time from the UI.

I may have figured out what is interacting with it to slow it down. Steam autostarts on login to the tray. When I close it Krita is normal again. Disabling autostart and Opening Krita first after login has normal results, even opening steam after, everthing seems normal. Starting Steam first after login, then Krita seems to cause the slowdown in the UI.

Could you also try with the appimage? I cannot reproduce this on KDE Neon (I don't have Fedora) and the appimage, in either an X11 or Wayland session. We don't maintain the flatpak ourselves, either. Do you observe the same issue with other Qt based flatpaks?
