i set fullscreen, exit the game as fullscreen, yet OW continually reverts to bordrless windowed.
no other game i have displays this behaviour.
I have this issue too, about 60% of the time when I load up OW2 its in Windowed mode even though I have it set to Full screen mode the last time i exited.
I do have 2 screens both with diff rez’s not sure if this is causing any issue however dont remember ever having the issue with OW1 with this same set up.
Meh though its not a major issue as I can just switch it back to Full Screen for each session when it happens.
