MuseScore unusable on Windows with large screen-elements
If MuseScore is used on Windows the display size is increased (because the user has poor eyesight), MuseScore becomes pretty much unusable.
The smaller problem:
Some text just gets abbreviated until you have to guess what it even means.
In the following image, this problem could be prevented by using a plus-icon for the button instead of some enormous text.
The bigger problem:
Most pop-ups grow too large, which results in the user being unable to click on the bottom buttons. Unless you know how to trick your PC, this makes it impossible to actually reach the "Okay"/"Next"-buttons.
