So I started playing a few days ago and everything was fine. Then, one time, I changed my game to windowed mode and then back to borderless fullscreen, after which weird spots started to appear on my screen, sometimes blinking and flickering. Here is a pic of those spots.
They come with a small fps-drop (from about 25 to about 15 fps, my PC is pretty low-tier) compared to before and neither changing any graphics settings, nor reinstalling the game or reinstalling my graphics driver did any good. Any Ideas?
EDIT: I also tried deleting the Vermintide-Folder in appdata, but that didnt help either
(made a Backup in case anyone would need some log files).
