Public bug reported:

Binary package hint: xserver-xorg-video-intel

Versions of the Intel driver later than 2:2.7.1-1ubuntu1 are unusably
slow for me. The first thing I do after starting X is normally to start
a pterm and maximise it; the first sign of trouble is that the scrollbar
takes ages to be replaced by normal black terminal area on maximisation.
After that, Xorg is using nearly 100% CPU, text scrolling is very slow,
etc. Typing this report is excruciatingly painful because it can take up
to a second for each character to appear, especially when the typeahead
buffer gets at all full.

EXA vs. UXA makes no obvious difference.

There are some rather odd visual effects as well: lots of letters are
the wrong colour. This may have only started after switching VT away
from X and back; I'm not quite sure. Bizarrely, this is visible in a
screenshot (I'm not using compiz or anything fancy like that), which
I'll attach to this bug.

Downgrading to 2:2.7.1-1ubuntu1 puts everything back to normal.
