Problem: I have dual monitors set up, playing minecraft java edition on windows 10. If I pause minecraft, go to my deskop, right click > display settings and I change the 'Multiple Display Settings' between 'Show only on 1' and 'Extend these displays', I can no longer open the minecraft session that is running and I have to right click on it in the taskbar and click 'Close window' and then re-launch it via the launcher. 

Impact: Forces you to re-launch minecraft. It does still save my progress so I don't lose anything.

Frequency: Medium-Low. I mostly use my second monitor for opening a wiki or youtube video while I am playing minecraft, so for me I do this often but I think a lot of users might either use 1 monitor or they might not adjust these settings while in a game.
