--- Comment #99 from Peter Nowee <peter.nowee at gmail.com> ---
I ran into this bug on a fresh install of Debian 8 (Jessie) RC2 on an EeePC 701
4G with Intel i915GM graphics. Linux kernel 3.16, X.Org 1.16.4, X.Org intel
module 2.21.15.

Using SNA instead of UXA, as suggested above, seems to still solve it:

# cat /etc/X11/xorg.conf 
Section "Device"
        Identifier "Intel Graphics"
        Driver "intel"
        Option "AccelMethod" "sna"
EndSection


I see that Debian is preparing to move to SNA [1]:

> xserver-xorg-video-intel (2:2.99.911+git20140529-1~exp2) experimental; urgency=medium
> ..
> * Stop overriding default upstream acceleration method (i.e. default to SNA
>    instead of UXA).

However, that change is still in Debian's "experimental" area, not in the
upcoming stable (Jessie) release.
