Hi Bryce,

Before the 11th I had not updated for more than a week (was away from
the system for a while) on the Intel laptop. The issue may have been
there for the Intel earlier and I did not notice it. I only picked it up
recently as I was resizing Firefox with many tabs on a large (1900x1080)
screen. The extra screen space in conjunction of having a relatively
complex app (if counting the web page) caused my hard drive to really
churn. I popped open System monitor to see the huge amount of swap space
in use. I quickly realised it was resizing the window that was causing
this. Most of the time I rarely resize windows (except to maximise) so
this could easily have gone unnoticed for a while.

The ATI system was left without updates for nearly two weeks before I
updated it on the 11th. Prior to updating the ATI system on the 11th I
was testing the system quite a bit and was doing a lot of resizing of
windows (admiring how smooth it was with compositing these days. Yay KMS
and DRI2). It was all vary smooth. I updated the system and tried the
same things again to look for regressions and soon found after resizing
the windows a few times the systems window performance took a dramatic
hit (dragging was laggy and very slow). So an update somewhere between
two weeks before the 11th had likely caused the regression for the ATI.
As I mentioned I'm not sure the ATI is exhibiting the exact same bug as
it does not leak memory. Performance simply takes a hit but both cards
exhibit the bad behaviour under the same conditions.

Is it possible to get a Daily live cd image from or before the 30th of
March? I could then test to see for sure if this issue was present prior
to the 31st update you mentioned.
