Similar problem but with nvidia after kde update. Disabling composite and acpid connection solves the problem for me. I use two 1440x900 screens.

Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"
DefaultDepth 24
Option "TwinView" "True"
Option "AllowGLXWithComposite" "False"
Option "AddARGBGLXVisuals" "False"
Option "ConnectToAcpid" "False"
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1440x900@60"
EndSubSection
EndSection

It is only needed to have Option "AddARGBGLXVisuals" on "False".

I am using:
-Nvidia driver version 173.14.27. (Nvidia GeForece FX 5500)
- X server version 1.8.1.902
- Two displays 1440x900 resolution.
- 686 system instead of x86-64.

When "AddARGBGLXVisuals" is on "True" both screens are flashing, changing the size of the items all the time. If you do not move the problem does not display.

Need more information or logs?

Same situation here (Intel i915 video on a EeePC 901). Xorg log showed X segfaulting:

Don't know if that helps or not, but there it is...

Exact same backtrace here (compositing enabled too). Going back to 1.8 solved it.

Looks like this bug:

The patch from that bugreport has been added to mesa 7.8.2-3. Please test.
Comment by Marc Cousin (cousinm) - Thursday, 26 August 2010, 08:07 GMT
I applied the patch myself a few minutes ago (not tried to build 7.8.2-3). X doesn't crash anymore, but display is extremely corrupted.

Will try mesa 7.8.2-3 as soon as I have the opportunity.
Comment by Marc Cousin (cousinm) - Thursday, 26 August 2010, 08:11 GMT
Exactly the same with mesa 7.8.2-3 : xorg doesn't crash anymore, but is blinking like crazy, and totally unusable. The output is corrupted.
Comment by Jan de Groot (JGC) - Thursday, 26 August 2010, 16:37 GMT
I don't know if the flickering is a bug in the intel driver, xorg-server or KDE, but I've already seen a bugreporting mentioning flickering with one of the nvidia-legacy drivers (17x) and xorg-server from extra, so I assume KDE is using something that is not supported by either driver.
Comment by Marc Cousin (cousinm) - Thursday, 26 August 2010, 17:16 GMT
It's not a simple flickering, it's complete corruption. Everything is messed up. Maybe blinking is not the right term.

exactly... no crashes anymore, but totally unuseable.
I also noticed recently update problems in firefox (only half the page scrolls, etc) but this was already with earlier versions of intel-dri but looks similar and might be related... don't know...
Comment by Lars Jacob (jaclar) - Friday, 27 August 2010, 23:05 GMT
well the good news: composition works for me again
bad news: it's fixed in the git repositories from mesa (AUR package mesa-git (7.9-devel))

I'm using xf86-video-intel-git, intel-dri-git, libgl-git and mesa-git now. There are no crashes and no screen corruption, but the blur effect doesn't work anymore. All blurred background is rendered black.

With xf86-video-intel 2.12.0-3 everything is fine again, but slower than with the git packages.
