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]

[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.
