<span class="quote">>=xf86-video-intel-2.20.18 installed with '--enable-sna' causes flash fullscreen video to freeze and sometimes crash Xorg entirely.</span >

When the fullscreen video freezes it can be woken up by issuing some Xorg OSD
(eg.Gnome/KDE volume display) but immediately freezes afterwards.
The audio continues playing in the background, just the video freezes.

The version of Adobe Flash does not matter, tested with 11.2.202.261 and
10.3.183.50.

The version of kernel does not matter, tested with 3.4.11 and 3.7.1.

The bug occurs in multiple browsers.
Tested with Firefox, Chrome, Chromium and Opera.

Does not affect any xf86-video-intel version built with '--disable-sna'.

Using IntelĀ® Ironlake Mobile GPU.

Bug does not occur if X11 compositing is disabled.

Xorg crash backtrace attached...</pre>
