[kde-linux] intel 945GM+current xorg git: display garbled w. KDM themed login screen

[Jens Stroebel]

		Hello.

Due to serveral reasons, we are using the most up-to-date xorg that we
can get, which means checking out the git-tree of the project(s) which
together build xorg.

We are using KDE-3.5.7 as the desktop solution and KDM as the login
manager and had to notice that the greeting screen of KDM gets garbled
with image data after the first logout, if "UseTheme=true".
A non-themed KDM displays correctly.

Said image data is obviously from the session that was last terminated
which gets "shuffled" with the background of the themed login screen.
Attempts to capture a screenshot have failed, unfortunately.

When logging in, the effect vanishes (the screen gets set up correctly);
after logging out again, the background of the KDM login screen is
garbled again.

lspci for graphics chip: 00:02.0 VGA compatible controller: Intel
Corporation Mobile 945GM/GMS/940GML Express Integrated Graphics
Controller (rev 03)
==============================
kde version 3.5.7
qt version 3.3.8
xorg (current git)
xf-video-intel (current git)
linux-kernel 2.6.21.5

Any ideas where this could come from?
Any obvious differences in the way KDM paints the screen with it's login
theme contrary to how the KDE session paints it's screen afterwards?

		I'd be grateful for any insights ...
