Comment 26 for bug 37218

After resuming from software suspend (which involves switching to text VT and
back) DRI works only partialy. Simple applications (like glxgears or gl-117 (the
3d game with rather simple 3d graphics)) work well, but more complex
applications don't. For example, Blender doesn't draw labels on buttons, draws
some garbage instead of menus and outputs some garbage in the top left coner of
the screen (above all other windows). More complex 3d games (like tuxracer)
cause immediate lockup. Before suspending (and after restart of Xserver)
everything works well.
