It is caused by the fact that my "first monitor" is actually my secondary monitor, but they are swapped in the windows display settings. Any idea why that happens? How can I change that behaviour?
Running MTA on my actual first monitor, with UltraThing installed, works perfectly fine.

This problem got solved by basically switching my HDMI-Ports for my 2 monitors... Can someone explain why this happens?
Did not expect it to be that easy, lol
