I have tested this now with Wine 1.5.15 and the Guild Wars 2 launcher. The launcher is still black and flickering at default or isn't this ticket related to this problem?
It's supposed to be fixed when the launcher/game is started with "-dx9single". The flickering observed when omitting the parameter is probably unrelated to the bug discussed here.
