I've installed the latest release:
$ calibre --version
calibre (calibre 3.11.1)

I'm running KDE on Wayland (instead of X11). I have Xwayland installed in order to run X11-only programs like e.g. Firefox.
Starting calibre results in a failure:
$ calibre
This application failed to start because it could not find or load the Qt platform plugin "wayland"
in "".

Available platform plugins are: linuxfb, minimal, offscreen, xcb.

Reinstalling the application may fix this problem.

Normally, Calibre should come up in its own Xwayland instance if Wayland ist not supported. In this case, as Qt-app, it should support wayland out of the box if the appropriate platform plugin was installed.
However, as the plugin appears to be missing, I have no idea why it wouldn't come up in Xwayland then (or how to configure that). Is this a misconfiguration?
Thank you in advance.
