Hello,
To make the long story short, I have had the same problem with version 9.0.188 under wayland (but not X11) on the server side, but upgrading to 9.1.24 has solved the problem. Gott sei Dank!
I’m not as happy with wayland as the OP says he is, but since Kubuntu is rumored soon to cease to provide X11 in default installs (maybe starting with 25.10?), I figure it’s time to get with the program.
Many thanks to those who made this work!
Albert
