Very likely (see attachment 79573 [details]). The title is wrong, GLX_EXT_swap_control is
only requested by the Steam overlay and non-critical. I can see the
GLX_EXT_swap_control with any game I launch through Steam (e.g. Oil Rush) and
the others work well. It's just Anomaly that is hitting a bug in r600g (or a
bug in Anomaly which isn't handled gracefully by r600g?). Anyway, the title
should be changed to something more accurate.
