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.
...

This 'UXA' workaround makes the graphics rendering work in my old IBM
Thinkcentre with old Intel graphics.

-----

But the current daily build does not solve my problem. There has never
been a garbled screen in my case, only the ugly rendering, and it is
still there, maybe there are only 256 colours. Even Lubuntu's default
background picture looks bad. I guess this old Intel chip will need UXA
also in the future.

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:
  Incomplete

Bug description:
  In my testing with the Intel driver using its default acceleration, what works:
  - 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 11.2 works on Raring with the 3.8 kernel (in Chrome)

  what fails:
  - 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.
