EXA got slow in 7.0

[Pierre Ossman]

Was there any major tweaks to EXA right around the release of 6.9/7.0? I
was running CVS versions during the RC-phase and EXA worked rather well.
But now I upgraded to 7.0 and rendering is terribly slow.

It's most noticeable with nautilus windows where you can see the window
getting slowly repainted. It seems to be a slow blit since it's a
sweeping rendering of the entire window, not drawing of individual elements.

This is a fedora rawhide machine with radeon mobility 9200.
