Some really few Flatpak apps used their own cursor instead of the Breeze one (which is absolutely the best).
So I followed bad advice online and did:
flatpak override --user --env=XCURSOR_PATH=~/.icons flatpak override --user --filesystem=/home/$USER/.icons/:ro
The result is that all apps use some kind of fallback cursor, black, the point-finger looks really old.
I already resetted all my apps using this script:
#!/bin/bash app_list=$(flatpak list --columns=application) for app in $app_list; do flatpak override --reset "$app" &&\ done
But the cursors stay the same.
Do you know how to get the cursor theme back? I think its some KDE runtime or something, but I am unsure.
