#PrStien :
Playing windowed is fine, just you can see the top bar during screenshots. No errors on log, and 1920x1080, I'm assuming the resolution is the reason why, I tried both options and the MWM Resolution changer.
I mostly use 1776x1000 windowed, but i can use FHD reso, full screen, without any problem.
I know it sounds like a dumb question, but, does your gpu/monitor support FHD reso?
In case they do then you might have to update your drivers. I dont know how to help further than this.
