** Description changed:

+ [Impact]
+ Just before the 2.9.0 driver released, a major performance regression was isolated and fixed regarding software fallbacks for certain types of cairo rendering ( http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/commit/?h=2.9&id=57fc09cef28bad2e3e8455b93ef2927118f8a3a3 ), but it introduced a new regression causing some things to not get rendered correctly which affected quite a few applications such as gwibber, GTG, and gnome-mastermind. This was fixed shortly after the 2.9.0 release which was included in Karmic and included in the xserver-xorg-video-intel 2.9.1 release.
+ 
+ [Symptoms]
+ No profile images loading in Gwibber, Colored boxes missing in GTG, missing board graphics in gnome-mastermind, no red boxes displayed in the testcase.
+ 
+ [Test Case]
+ 1) Boot a Karmic system with intel graphics
+ 2) Download testcase attached to comment #13 (CellRendererTags_testcase.py)
+ 3) Run with the command "python CellRendererTags_testcase.py"
+ 4) 4 red boxes will be shown if it is rendering correctly.
+ 
+ [Patch]
+ http://launchpadlibrarian.net/37466430/xserver-xorg-video-intel_2.9.0-1ubuntu2.1.debdiff
+ 
+ 
+ [Original Report]
  See the test case at comment #13.
  
  In that test case, a simple python script using pygtk bindings is using
  Cairo/Gdk to draw red squares in a Gtk widget.
  
  This script is working for any Ubuntu version prior to 9.10.
  In 9.10, this script is working for ATI and NVIDIA gpu or under Xnest. But with any Intel GPU, the square are not displayed (see screenshot in comment #14 )
  
  This bug is pretty severe as it makes applications like GTG (and
  probably others) unusable on a intel Karmic desktop.

** Summary changed:

- [Needs -intel 2.10] Cairo/Gdk shapes not visible on Intel gpu since Karmic
+ [Needs -intel 2.9.1] Cairo/Gdk shapes not visible on Intel gpu since Karmic

[Needs -intel 2.9.1] Cairo/Gdk shapes not visible on Intel gpu since Karmic
