I use the xorg-server 1.5.0 / Xorg 7.4 (but had this problem with 1.4.2/7.3, too) together with the free intel driver (2.4.2-r1) on a IBM/Lenovo ThinkPad T61 which has an Intel X3100 card. Since about three weeks I have some very strange redisplay problems. - I close a window, but it's still displayed. When I move another window over it, it'll be erased. (It's like cleaning a chalkboard.) - I follow a link in a webbrowser, but the old page is still displayed. In order to see the new one, I have to move the window. - I compile something in a terminal and some lines are not refreshed. Again, moving the window forces a redisplay. It seems to be not depended on the applications I use. It always happens with konqueror, urxvt, emacs, firefox running inside stumpwm or XFCE. I'm not completely sure since when these problems occur, but downgrading to intel drivers 2.4.1 doesn't work, too. These problems only occur, if I have no second monitor attached! At work, I use my laptop lcd as second monitor left of a big additional tft. Then redisplay I allright. I tried making a screenshot, but the screenshot looked correct, whereas what I saw on my monitor was really broken...

Did you downgrade only the driver package? Or have you tried using the old driver with the old xorg and it still doesn't work?
Just the drivers, but I did that several times. All I can say is that I've had the problem with xorg-server-1.4.x (where x is 2 or 99, I'm not sure) and 1.5 with the intel drivers in version 2.4.1 and 2.4.2.
I do hope you meant x11-drivers/xf86-video-i810 (xf86-video-intel is not a package name in the current Portage tree). It's probably interesting to post your xorg.conf too.
And the Xorg.[0-9].log as well, please.
Yes, I've meant the x11-drivers/xf86-video-i810 ebuild. I'll attach a Xorg.0.log which belongs to a session where the problem occured. In that session first everything was alright. I had to close the notebook and reopen it to trigger the bug. And I'll attach my xorg.conf. It's quite basic and I didn't change anything in it when the problem occured in the first time.

Created attachment 166066 [details] A log file of a session which showed the redisplay problem
Still the same with xorg-server-1.5.2...
This problem is known to the Xorg guys. It's https://bugs.freedesktop.org/show_bug.cgi?id=16257 in their tracker. The suggested workaround Option "FramebufferCompression" "off" in the Device section fixes the issue for me.
Alright, let's track the bug upstream then. Thanks
