i tok my time to record the issue with my phone
it only happens in fullscreen, but i need to use fullscreen for shadowplay
the problem is that in fullscreen copy/paste is fucked up, so is whenever i click F1 i have to click f1 multiple times in a row before it responds to my buttonpress, same with escape menu it doesnt pop up again the menu it just refuses to close

edit: i made a thread on facepunch, if you have this problem go ask on my thread there, also possible to write here, if it works ill post it there.
