I did test the latest mainline kernel, but as of this moment don't have
a clue about how to test the latest Xorg stack or bisect a regression.
(Though if I wanted to get a clue about bisecting a regression, I could
follow your link regarding that, thanks.)

The online archive of the email begins with my email at
http://lists.freedesktop.org/archives/dri-devel/2013-August/043876.html

Happily for me as regards my time investment on this problem, but
perhaps unhappily as regards fixing the problem, Chris Wilson from the
Intel Open Source Technology Centre rendered this summary judgment in a
reply:

"It's a flash bug. They ignore the format of the Window that they
PutImage to. (Worse, they create an image of the right depth or else X
would reject the PutImage with a BadMatch and then render incorrect
pixel data into it.)"

If his assessment is on the mark, and if you have a PC with affected
Intel graphics that you want to display Flash content, it would seem
that the only recourse is to install a supported non-Intel video card.

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:
  Triaged

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.
