I have the same exact crash when trying to launch PMP on KDE on Wayland. If I launch using KDE on X11, I do not have the issue.

PMP does not work with Wayland. It may be possible to make it work by building against a newer Qt. It's is likely better to switch to X11 because Wayland obliterates some useful features in a playback application (like refresh rate matching).

I understand that this is now probably a "resolved wontfix" situation, but I really think discarding Wayland wholesale is the wrong approach, especially since X11 is slowly being phased out. It would be nice if the app could run without crashing under XWayland in the meantime.

Wayland is by no means perfect at this point but it is a constantly maturing technology, and having this stance will become increasingly difficult as distros such as as Ubuntu move to making Wayland the default.

If Wayland support is off the table, making the app work with XWayland is much better than having a segfault-on-launch default situation.
