Musescore 4.6.3 and Wayland native Niri WM

[aha917]

I use Cachyos, and Niri [have Gnome 49 installed as well].

When I start Musescore in Niri it often times doesn't show the drop down menus completely, rather just part of it's top elements [see screenshot].

Interestingly enough, if I press many times on the button, every now and then the drop down menu shows it's full content. Weird :)

When I check the exact Revision of MuseScore Help > About MuseScore Studio...
OS: **KDE** Flatpak runtime, Arch.: x86_64, MuseScore Studio version (64-bit): 4.6.3-, revision: github-musescore-musescore-

Why does the OS output here points to KDE? Was the AppImage build on KDE perhaps?

Also, when starting MuseScore under Gnome 49, there are no problems showing the full content of the drop-down menus. Any ideas, how to engage this problem?

env | grep QT
QT_QPA_PLATFORMTHEME_QT6=qt6ct
QT_QPA_PLATFORM=xcb
QT_WAYLAND_DISABLE_WINDOWDECORATION=1
QT_QPA_PLATFORMTHEME=qt6ct

On my end (also niri) its slightly different but still odd 😆

Apparently,
downgrading to MuseScore 4.5 solves the dropdown menus problem.
