Hi,
Confirming this bug.

Running on
https://launchpad.net/~xorg-edgers/+archive/ppa
(newest xorg, intel driver and kernel)
(so only UXA and DRI2)

I have some xrandr configurations bind to keyboard shortcuts, so it's
easy for me to test without restarts.

Without compiz, everything works (curently running 2048x768 dual). Even
resolutions greater than 2048x2048.

With compiz:
1. xrandr --output LVDS --mode 1024x768 --primary  --output VGA  --mode 1024x768 --right-of LVDS
Black or corrupt screen (but mouse shows it is in correct resolutions next to each other).

2. xrandr --output LVDS --mode 800x600 --primary  --output VGA  --mode 1024x768 --right-of LVDS
WORKS
3. xrandr --output LVDS --mode 1024x768 --primary  --output VGA  --mode 800x600 --right-of LVDS
WORKS
4. xrandr --output LVDS --mode 1024x768 --primary  --output VGA  --mode 1024x768 --same-as LVDS
WORKS
5. xrandr --output LVDS --mode 1024x768 --primary  --output VGA  --mode 1360x768 --above LVDS
WORKS - today morning worked :)

For compiz settings "loose bindings" or "indirect rendering" in any
configuration have no effect.

Tested xserver-xorg-video-intel - 2:2.7.99.1+git20090528.704771f1-0ubuntu0morgwai1~jaunty1
No change.

Tested kernels 2.6.30-9 and 2.6.30-8 with no difference.

X log shows nothing interesting.

If you need anything to test, I'm availiable.
