--- Comment #8 from Henri Verbeet hverbeet@gmail.com 2013-08-12 08:12:15 CDT --- Something seems to go wrong when creating a GL context through glXCreateContextAttribsARB(), although context creation doesn't actually fail. Does it make any difference if you run with WINEDEBUG="-all"? Unfortunately I don't have an X server that's new enough to reproduce this with.
