The Enlightenment DR16 window manager uses a pager which takes snapshots
of the active windows, and displays miniature versions of these windows
in the pager. After upgrading the video driver, this functionlality has
broken, and the pager simply displays black squares for window
snapshots. This worked perfectly with xserver-xorg-video-i810 1.7.2-4,
and has broken since upgrade.

Does this still happen with latest intel driver from Lenny?
And from unstable or experimental?

Yes, however I have some additional information which suggests the bug
is not actually in the driver.

I recently upgraded the version of the driver on my main desktop
machine, which is using an ATI card with the radeon driver. As the
radeon driver defaults to XAA, I forced the driver to EXA mode with:-

Option "AccelMethod" "EXA"

After restarting X, I immediately saw the same bug, which I've
previously seen on an Intel based laptop and a desktop with Intel
onboard graphics. Package versions are:-


xserver-xorg-video-radeon       1:6.12.2-2
xserver-xorg			1:7.4+3
xserver-xorg-core		2:1.6.1.901-3

Start of xdpyinfo output:-

name of display:    :0.0
version number:    11.0
vendor string:    The X.Org Foundation
vendor release number:    10601901
X.Org version: 1.6.1.901


So, this appears to be a bug with EXA on *any* driver.
