Critical failure of musescore 3.0.2 while using second screen.
So I have two screens that I work on. Since I compose on Reaper 5, I later input the notes into musescore by hand. This is a tough process and I have to click back and forth between the two screens to make sure I'm accurate.
However, upon running musescore 3, and editing for a bit, I click back to reaper to see what I have to input next and, after returning to MS3 none of the notes will play back for you after clicking, and the play button does not work. All the sound is gone. After about five minutes of this use, it will randomly stop responding and crash.
Here is a video of me reproducing the problem. When you don't see the mouse that is because it is only recording for one screen.
