After contact support they ask to make new post about this problem.
After teleport i often get stuck on a blackish screen, and the only option i can take in the ui, is leave game. It makes the game no fun at all, i need to restart the game like 4-12 times an evening. What i found on the forums, its mainly a problem with amd cpu/gpu, and something about membory getting full.
Maybe blizzard can take a look again at this problem.
