Comment 201 for bug 745608

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"

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.
