--- Comment #28 from Matthew Dawson <matthew@mjdsystems.ca> ---
I think this may have been solved with the latest ddx for ati.  I was
originally using version 7.0 (or earlier) along with the latest mesa (9.2, rc
or gold) and glamor (0.5).  With KDE I would get frequent slow downs, with X
consuming a full CPU core.  Using perf, I noticed it spent all of its time in a
memcpy, and using gdb I found it was copying memory between textures in glamor.

Upgrading to the latest ddx (7.2), all speed issues in KDE (including konsole)
mostly disappeared.  X no longer uses cpu like it did before.  For those still
seeing speed problems, what version of the ati ddx are you using?  And if you
upgrade to 7.2, do your speed problems go away?

I'm using Gentoo with an HD7970.
