Using Gnome Ubuntu, Dell XPS 13, intel 915 Graphics
After upgrading from 14.04 to 14.10 there are a lot of places where the graphics are working much slower than they were before:
- Gnome Shell Interface is very sluggish, visible "chops" (redrawing) when pressing the [Super] key.
- Selecting text in Gedit takes a full second pr. line
Experiences some subjective improvement when I booted kernel 3.13.0-37 instead of 3.16.0-23, but that may be my imagination as the problem persists.
I've searched google, forums, found a couple of relevant links that point to the issue being the Intel drivers.

But the drivers currently in 14.10 should be newer than those supplied by Intel to 14.04 so that doesn't make sense to me. As one Intel developer wrote:
"I would like to point out that since what we do is bring more ecent versions of the software to the target distributions than they ship with, a 14.04 targeted installer is unlikely to bring much to a 14.10 installation, which most likely has the same or more recent versions already anyway."
