Created attachment 170484 [details] Resizing settings until there's nothing left SUMMARY The settings dialog does not have minimum values for width and height set, so it's possible to resize it until there's only a small strip left, even "eating" the close button itself. STEPS TO REPRODUCE Open the Settings panel and resize the window by moving the mouse cursor to one of the 4 corners and drag OBSERVED RESULT The window including (the titlebar and the window control buttons) disappears EXPECTED RESULT Just like in the main application window, it should not be possible to make the window smaller than a fixed threshold. At least the titlebar and some part of the application should remain visible. The QT application Kasts (https://flathub.org/apps/org.kde.kasts) has a similar settings dialog with minimum width and height set, so it might be possible to copy code from there. SOFTWARE/OS VERSIONS Arch Linux with Gnome 46 on Wayland and Version 24.05.0 installed from Flathub.
I could reproduce the issue in GNOME Wayland but not in Plasma, so the issue is specific to that environment.
Since multiple Apps are affected, lets track this in one place. *** This bug has been marked as a duplicate of bug 488466 ***
