@Michel, I also found this bug in Tappy Chicken, an Unreal Engine Linux build demo. http://upload.nowaker.net/nwkr/1404422235_tappy.png http://upload.nowaker.net/nwkr/1404422288_tappy2.png Since the game is dead simple, apitrace will probably more usable than from BFBC2. You can find it here: https://wiki.unrealengine.com/Linux_Demos http://ue4linux.raxxy.com/tappy_chicken.zip
