When playing the game and using skills on melee characters, the client becomes black for a few moments, and then return to normal. If it's not black, it is showing a game option menu opened some time ago…
What I've tried
Update windows and drivers
Run on lower resolution
Run on lower settings (default/high-end graphic, no difference)
Tried on external display with lower resolution
Window full screen, full screen
