[Problem]
On Jaunty 64 bit with Intel GM965 and UXA enabled Blender is not usable because all GUI elements change their position on hovering. This does not happen with EXA.

glxinfo | grep GLX_EXT_texture_from_pixmap
   GLX_ARB_multisample, GLX_EXT_import_context,
GLX_EXT_texture_from_pixmap,
   GLX_SGIX_visual_select_group, GLX_EXT_texture_from_pixmap
   GLX_EXT_texture_from_pixmap

All the pop-ups and menus seem to be absolute positioned from the top
left of the screen and not from the top left of the blender window
content. Have a look at the screenshot. I tried to visualizing it. All
red rectangles have the same size.

I still have exactly the same problems after installing
* libdrm2_2.4.9-1ubuntu1~xup~1_amd64.deb
* libdrm-intel1_2.4.9-1ubuntu1~xup~1_amd64.deb
* xserver-xorg-video-intel_2.7.0-1ubuntu1~xup~1_amd64.deb
