Using higher DPI scaling causes MuseScore's musical notation to render incorrectly. Below are two sample screenshots at the same absolute zoom level. The first is at 125%, the second at 100%. The one rendered with scaling is blurrier and has jagged edges for notes.

It's noteworthy that this doesn't apply to any text on screen, including staff text, dynamics, the title, etc, which renders normally at high DPI; only the staff notation looks blurry.

I've already tried the command line -D and -x options to attempt to fix this, however those simply scale everything and don't change how the music renders, so I've reverted to 100% scaling system-wide and increased the font size so that everything is still usable.

System/Musescore info:
OS: KDE neon 5.26, Arch.: x86_64
MuseScore version (64-bit): 3.6.2.548021370, revision: 3224f34
Linux Kernel Version 5.15.0-53-generic
Intel Core i5-9300H
Intel UHD 630 Graphics

This was also never a problem when I used Windows 10 with 125% scaling.
