SUMMARY Attempting to close certain Settings windows in digikam causes the window to flicker and the application to freeze, making it unusable. From journalctl, I saw that there were some wayland compatibility error messages. E.g. Dec 21 07:52:56 fedora digikam[50990]: qt.qpa.wayland: Wayland does not support QWindow::requestActivate() I'm not sure if that's a red herring, but after some digging [1] I found that starting digikam with `-platform xcb` fixed the issues. I reported this bug in the fedora tracker as well, which led me here [2] [1](https://discussion.fedoraproject.org/t/bug-with-qt-software-digikam-texstudio/74839/2) [2](https://bugzilla.redhat.com/show_bug.cgi?id=2255516) Steps to Reproduce: 1. Launch digikam 2. Navigate to Settings -> Configure Digikam 3. Close the Settings window, using the X icon in the top right Actual Results: Flickering Settings page. App freezes. Expected Results: Settings page is closed. App does not freeze.
