New score window invisible, display size ballooned

Musescore was working fine a few days ago. I recently opened up the app and a few things caught my attention:
First, when I went to open a new score, the new score window was invisible - the main window grayed out as Windows usually does for a smaller popup window, and using alt + f4 closes the ghost window and allows me to access the main application.
Then, the blue loading screen window failed to close when I started it up a second time, leaving me unable to access the main application when both windows were open.
Finally, something shifted and caused everything in the UI to nearly double in size.
I've tried restarting my computer, uninstalling and reinstalling, and nothing.
