Qt version's controls in titlebar don't appear in KWin Wayland

I ran the Fedora 35 gimagereader-qt package (gimagereader-3.4.0-1.fc35.src.rpm) for the first time in several months and had a hard time figuring out how to work it. Then I realized, based on the screenshots in https://itsfoss.com/gimagereader-ocr/ , that a lot of its UI is controls in its titlebar. But for some reason, on KDE Plasma Version: 5.24.3 KDE Frameworks Version: 5.91.0 Qt Version: 5.15.2 on Wayland none of these controls appear: I'm sure there used to be more controls in the app before, but I can't remember its old appearance. Here is the console output when I run it; maybe output likeWayland Interface: zxdg_decoration_manager_v1 / 7 / 1 is significant.

I tried forcing the app to run using X11 with env --unset=WAYLAND_DISPLAY && QT_QPA_PLATFORM=xcb gimagereader-qt5 ; if that worked, its behavior didn't change. GTK apps like gnome-abrt continue to display controls in their titlebar fine on KWin Wayland.

As a workaround, I installed the GTK version with sudo dnf install gimagereader-gtk and that shows all the controls in its titlebar. But it pulled in 15 MB of unneeded libraries.

Can you try deleting $HOME/.config/gImageReader/gImageReader.conf, perhaps the window geometry stored therein is messed up. Otherwise I can't really think of anyway gImageReader can control this, most likely an issue with Qt/Wayland.

Thanks for responding.

I tried, didn't help.

I don't think there is anything I can do about this on gImageReader side.
