This is still an issue, help please.

This issue appeared shortly after a windows 10 update. The current settings were working fine beforehand. When I start a match, the game shows up in the top left of my screen and covers only about 1/4 of the screen. I can still see the desktop in the background. Please see this video that shows the problem:

The yuri sniper range is way too far now. Deso doesn't even stand a chance

Please add this thank you
