Fix for running AppImage under Debian - and a question

• Sep 12, 2023 - 00:45

If I run the linux AppImage for Musescore 4.1.1 (on Debian Sid, KDE Desktop running Wayland), it errors out with the following output:
mark@desktop:~/Downloads$ ./MuseScore-4.1.1.232071203-x86_64.AppImage /lib/x86_64-linux-gnu/libjack.so.0
/lib/x86_64-linux-gnu/libnss3.so

/tmp/.mount_MuseSc6EBSpz/bin/mscore4portable: symbol lookup error: /lib/x86_64-linux-gnu/libEGL_mesa.so.0: undefined symbol: wl_proxy_marshal_flags

But I can run it successfully if the command I enter is:
LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libwayland-client.so.0 ./MuseScore-4.1.1.232071203-x86_64.AppImage

I'm not very well informed on AppImages, but is this something that could be fixed in future AppImages?
Also, although I can now run Musescore 4.1.1, there is a strange bug in that all of the pull-down menus (File, Edit etc) now have their contents appear in the centre of the window, rather than directly under the menu bar - see attached screenshot.
