Hello @Celexi, are you still experiencing this issue on an up to date system?
Closing pending feedback.
Nothing extracted yet.
I reported this in dota 2, but no one saw it, so i am reporting here, this issue is old and annoying now, sometimes the overlay when getting a new message, will promptly crash dota2, alt tabbing with the overlay enabled is a casino slot machine on if its going to not crash or not when back in game, this is horrible.
