Created attachment 171574 [details] Screenshot SUMMARY I installed okular as flatpak, using Gnome 45 on Fedora 39. I had no problems with okular. Today I couldn't start okular. The window was invisible or not there. In Gnome overview it reserved the space for the window, but it wasn't there (see screenshot). I moved .var/app/org.kde.okular away. Then okular started normaly. I compared the config dir and found the problem in .var/app/org.kde.okular/data/okular/okularstaterc This is the content: -------------------------------------------------------------- [MainWindow] 2 screens: Window-Maximized=true RestorePositionForNextInstance=false State=AAAA/… -------------------------------------------------------------- If I remove the line "2 screens: Window-Maximized=true" or change the value to "false" it works. Sorry, when I don't follow the STEPS/Outcome template.
