do "-windowed -noborder" in launch options, to play fullscreen windowed mode
I also have this problem. Though i verfied the integrity of the game files and it found that there were 2 missing ones. I haven't played since then so i dont if that worked or not
did u recently update nvidia drivers?
To people that give a shit: I goodgled it and as i can see some people have that problem aswell (check reddit). The way to fix it for me was to delete avg antivirus (don't mind that i had that shit on pc). I did that because my csgo started minimalize like crazy since avg installed their weird af web browser so I deleted that browser and antivirus. Worked for me.
Borderless is definitely the best, I literally can't play without it. I guess I have an addiction.
