[MU4 Issue] Interface is not scaled correctly on some high DPI systems

I have three different high resolution systems (> 150 DPI). One two of them - the two Linux systems, MU4 displays unusably small by default. On the WIndows system, it seems OK.

This is an extremely common, we get reports about it for MuseScore 3 pretty much every single day. So we provided a command-line option "-D" to workaround it; actually also another "-x". But -x is no longer supported it seems, and -D no longer works (see https://github.com/musescore/MuseScore/issues/10354).

It would be great not to need workaround like -D so much. So I'm submitting this issue as a place to track systems where it doesn't work.

For me, it's two Linux systems, both actually Chromebooks running Linux via the supported "crostini" container mechanism for this. First is a Pixelbook Go, second is a Lenovo Duet. Both display the problem using the default screen resolution.
