Changing the DPI in Windows, spoils the appearance of the application, prevents you from using it. On 65 "screens, I have to change the DPI scale in Windows 10. Changing the scale means that the application does not work correctly. I cannot use the graphic symbols because they cannot be seen.
Below I enclose print screen.

Actually, maybe something else is going on here. The code handling this scaling is trying to achieve a particular goal: icons the same physical size (and score displayed "life size") regardless of monitor resolution. That's a reasonable goal for any monitor resolution or size if you view it from a "typical" distance. But, a 65" screen you are probably going to view from farther away than a typical laptop screen or desktop monitor. And thus, maybe you really do want bigger than normal icons, so they are visible from across the room.

Probably we should have some sort of automatic logic to deal with that. But meanwhile, using the -D option should allow you to trick MuseScore into scaling things however you like. Note there are other relevant settings too depending on your OS and the specifics of your display settings, you might also try the -x command-line option and/or the environment variable QT_AUTO_SCREEN_SCALE_FACTOR=1. There is also now a scaling option specifically for the palettes, in Edit / Preferences / Advanced, and of course also font and icon size settings in Edit / Preferences / General. So, one way or another, it should be possible to achieve just about any look on just about any system, with just about any display resolution and viewing distance.
