I’m running Fedora 35 (5.16.11-200.fc35.x86_64) with Gnome 41.3 on an AMD CPU 1950x, with two Nvidia cards and > 100GB RAM.

For about six weeks, I’ve been unable to use Calibre.

The problem was that (somehow) Qt thought my system was using Wayland when it was actually using X11. So Calibre didn’t launch at all; the debug just gave misleading messages. Once I managed to install Wayland (tricky, because of Nvidia issues), I got my library back.

Alas, I can’t do much with it: The two parts I use most (ebook-viewer and ebook-edit) produce unreadably mangled windows, even though the main library window looks just fine.

I had exactly the same problem with the Chrome browser (though not Firefox), which I could fix by passing it a couple of command-line arguments (--enable-features=UseOzonePlatform --ozone-platform=wayland).

Is there a similar workaround for the satellite apps? Is there any difference in the way the main window, on the one hand, and the viewer and editor, on the other, interact with Qt, the OS, and/or the windowing system?

I doubt this has anything to do with the desktop environment, but I suppose I could switch from Gnome to KDE and see if that helps … Any thoughts?

Thanks!
Fred
