I have an odd graphics problem on my Debian laptop: I'm getting strange flickery pixels:

I don't get it with the kernel framebuffer but I do get it with X whatever window manager/desktop environment I use. I've tried restarting X, re-installing some X packages and even restarting the computer.
One thing I haven't tried which someone suggested was a live CD using a different XOrg version.
Any other suggestions or similar experiences?
What graphics chipset?
(II) intel: Driver for Intel Integrated Graphics Chipsets: i810, i810-dc100, i810e, i815, i830M, 845G, 852GM/855GM, 865G, 915G, E7221 (i915), 915GM, 945G, 945GM, 945GME, 965G, G35, 965Q, 946GZ, 965GM, 965GME/GLE, G33, Q35, Q33, Intel Integrated Graphics Device (II) Primary Device is: PCI 00:02:0 (--) Chipset 852GM/855GM found
Which driver version?
(II) LoadModule: "i810" (II) Loading /usr/lib/xorg/modules/drivers//i810_drv.so (II) Module i810: vendor="X.Org Foundation" compiled for 1.4.0.90, module version = 2.2.0 Module class: X.Org Video Driver ABI class: X.Org Video Driver, version 2.0
Has it only recently started or always occurred?
Just recently.
Do you have subpixel rendering enabled perhaps?
I don't think so. I found "XAANoOffscreenPixmaps" enabled in my "Device" section. (I think I may have added this ages ago when I tried compiz.) I tried disabling it but it didn't make any difference.
What does Xorg.0.log say?
I can't see any obviously related errors or warnings.
I tried an Ubuntu live CD earlier on and the graphics seemed fine with that so I'm hoping it's just an X problem. Maybe I could try installing a different version of X. Or different video drivers?
Thanks for your help.
Cheers, Richard
