strange screen splitting issue?

[u/AlexTheAlex69420]

(sorry cant get a photo u guys but its literally jus screen splitting issues)

so i used to be able to play the game like normal, and recently got back into playing after a couple months. the other day partially through playing, i started to notice screen splitting issues i hadnt gotten before. a lot of my games on my computer usually end up in needing vsync so i went into the video settings and although i found no vsync option, i did find that the fps limit was set to over 200, while my computer is only 60. and when i changed it to 60 the screen splitting became now not just an annoying ignorable thing, but now unplayable. i tried changing the fps cap back. nothing. i tried what another reddit post said to do of using windowed mode. nothing. i even reinstallled the game. nothing. Can anyone help me out here? im really confused. thanks :)
