UI bug

Bug description

A picture is worth a thousand words.

MuseScore 4.0.2 / Debian:

ms_fonts

Zoom in:

ms4-zoom

It clearly doesn't follow the system-wide settings. MuseScore 4 UI is rendered very differently from MuseScore 3 and pretty much every other application.

Compare to MuseScore 3.6.2:

ms3-fonts

Zoom in:

ms3-zoom

For every aspect of the UI, such as font antialiasing or "smooth scrolling", where the application fails to follow the system-wide settings, there should be an option to adjust it to the user's preference.

Steps to reproduce

Upgrade from MS3 to MS4.
