When i start a game I see the Loading Screen for arround 1 half Secound then simple all Pixels of my Screen start to Blink in different Colors. Happened the 3th Time to me now. Did a Game Repair didnt Helped so i cannot Play anymore. Normal Log in Screen Works /after game Screen too (they restarted 2 Times and flamed / reported me i cannot blame them but i cannot do anything about it i would like to play) I did set everything to normal Configs in the Data didnt help either idk what to do more. Sorry for the bad english i just wanted to finish it fast. greetings Deadmenken
