--- Comment #19 from Erich Hoover ehoover@mines.edu 2012-09-08 10:37:51 CDT --- Ok, we confirmed yesterday (conversations on IRC) that this is not either of the X bugs previously listed, so I've opened up a new freedesktop.org bug with a request for help (https://bugs.freedesktop.org/show_bug.cgi?id=54671). The problem appears to occur when both OpenGL and X11 are in use simultaneously and they happen to use the same sequence number for two separate threads (based on watching the Netflix Silverlight app).
