Title:
8086:2562 Flash 11.2 content displays in shades of green and purple
only, and in a horizontally compressed space
Status in “linux” package in Ubuntu:

Bug description:
In my testing with the Intel driver using its default acceleration:
- Flash 11.2 works on Quantal with the 3.5 kernel
- Flash 11.2 works on Raring with the 3.5.0-17 kernel (though it boots to a
low-res desktop with a frozen pointer)
- Flash 11.2 works on Raring also with the 3.6.11-030611 or 3.7.10-030710
mainline kernels
- Flash 11.8 works on Raring with the 3.8 kernel (in Chrome)
- Flash 11.2 fails on Raring with the 3.8 kernel
- Flash 11.2 fails on Raring with the latest mainline kernel, 3.11.0-031100rc5
- Flash 11.2 fails on Saucy alpha 2 with its default kernel
Disabling Flash *hardware* acceleration altogether (via R-click in the
Flash display window: Settings: General tab) did not fix the problem.
WORKAROUND: Setting the Intel driver's acceleration method to UXA
rather than its default SNA *always* fixes the Flash problem, but
causes a garbled login screen under LightDM that so far has no
workaround.
I also tried one possible fix for the default Intel SNA acceleration using
the TearFree option. I created /etc/X11/xorg.conf.d/20-intel.conf with
contents:
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "sna"
Option "TearFree" "true"
EndSection
But this had no effect.
