--- Comment #21 from Erich Hoover ehoover@mines.edu 2012-09-08 23:01:41 CDT --- Created attachment 41611 --> http://bugs.winehq.org/attachment.cgi?id=41611 Add the X11/GL lock back around XCheckIfEvent
Ok, I've narrowed down which routine is responsible for the lockup (XCheckIfEvent). The attached patch is a hack to add the lock back around this routine (against latest git).
I've also noticed that (at least for Borderlands, though not for Netflix) using libxcb-1.8.1 also fixes the issue. You can download and install libxcb-1.8.1 separate from the rest of the X11 libraries, so it should be possible for distros to push this update and have Wine put a dependency on it.
