Well… sometimes I run across some bugs with OW2 playing in Linux, for example:
Battle.net freezing before login
Everytime that I died the game stop detecting keyboard inputs, but after alt + tab the game detect again.
Random performance drops
Is nothing big but I not playing competitive anymore, I imagine if I was playing competitive I’ll be pretty pissed off if a bug like that occurred during a match(the battle.net case only if I had to restart the game/PC during a match)
