Bug Description
Binary package hint: xserver-xorg-core
System 1: Dell Inspiron 1100 w/Celeron 2.80GHz, Intel 82865G (disabled), NVIDIA GeForce FX 5200 PCI. Running Feisty with latest updates.
System 2: Dell Inspiron 510m w/Pentium M 1.5Ghz, Intel 82855GM. Running Feisty with latest updates.
Since the upgrade of xorg-server to 2:1.2.0-3ubuntu1, 2D rendering has become very sluggish and choppy for certain operations, particularly minimizing & unminimizing applications.
Steps to reproduce:
1. Open firefox and leave its window open & maximized
2. Open a GNOME terminal window (normal size), then minimize and unminimize the window while observing its choppy animation.
As you can see, metacity's black frame appears for considerably longer than it should while minimizing, approximately .5secs on both of my testing systems (sometimes it's even slower, hence having firefox open in the background).
I am having this problem on two of my systems, using the nv driver and i810 driver respectively. I'm attaching logs of my first system exhibiting this sluggishness, and if it will help, I also have logs from a fresh unmodified install of Herd 4 (using xorg 7.1 and exhibiting no slowness issues) if they're needed.

The mtrr hasn't changed since the upgrade, in case someone suggested it. Also, I have since installed nvidia-glx on my first system (which is a Dell Dimension 1100, sorry) which exhibits the same slowness issue.
Another note: on my second system, I tried the newest xf860-video-intel from git, and it doesn't help with 2D performance at all.
