SUMMARY

Both Flatpak and AppImage versions of Krita become unresponsive to UI input for ~25s after attempting to paste an image, creating a new image, or selecting a tool, or trying to use a tool, or really just about any interaction whatsoever other than hovering over menu items.

STEPS TO REPRODUCE
1. Open Kirta
2. Create a new image
3. Observe that UI is unresponsive and mouse cursor doesn't even appear

OBSERVED RESULT

Krita is unresponsive to UI input for ~25s at a time after just about any action and, during this period, the mouse cursor will not even appear in the window.

EXPECTED RESULT

Krita is responsive to UI input and doesn't freeze for 25s on ever action.

I cannot reproducce this issue on my Linux laptop or desktop with the appimage (both running KDE Neon). Could you attach the contents of help->system information for bug reports and help->krita log for bug reports to this bug?

Ok, so this is wild: Since the log was so useless I wanted to try and get more information, so I ran the flatpak from the terminal (flatpak run org.kde.krita) and the issue was not present.

I then closed that session and re-ran krita from the .desktop menu entry and could not reproduce the issue.

I even went and removed the flatpak, removed the .var/app/org.kde.krita directory, and reinstalled the flatpak and could not reproduce the issue.

This leads me to believe some other component may be at fault, but you've got me as to what.

Heh, I cannot guess either. Then let's just close this report. Thanks for testing again!
