Problem: After finishing a match and view my stats, I could not return to GW map nor the main menu. Only a black screen appears and the "task bar" at the bottom. It seems to me that the UI brakes here. Note: The game works fine, no issues with UI or performance and I did not had any crashes lately. My specs: Ubuntu 14.04, HD5770 with 14.06 beta ATI proprietary driver, PA 71937
Yeah, I have that too when using optirun to use my secondary graphics card. As you've probably seen from the bug report, resizing the screen fixes it.
