See image attached. Resetting to factory settings, restarting, and reinstalling didn't help. Theoretically, that means that just installing the program should be a reliable way of reproducing this issue, but I imagine that isn't the case since a bug like this would be immediately reported.

OS: Arch Linux, Arch.: x86_64, MuseScore version (64-bit): 3.4.2., revision: 148e43f

Citing from that:

The issue happens only when once of these environment variables are set :

XDG_CURRENT_DESKTOP=KDE
KDE_FULL_SESSION=true
DESKTOP_SESSION=/usr/share/xsessions/plasma

as workaround, you start musescore like this :
env -u KDE_FULL_SESSION -u XDG_CURRENT_DESKTOP -u DESKTOP_SESSION musescore

It seems qt 5.15 does something wrong with these settings.
