Xorg Log
Hi,
With anything newer than xf86-video-intel-2.99.911 including today's git, I get
random flickering on parts of the screen while playing Urban_Terror-4.2. I've
tried using glamor, sna, and uxa, no difference. I bisected it to this commit:
# git bisect bad
8369166349c92a20d9a2e7d0256e63f66fe2682b is the first bad commit
commit 8369166349c92a20d9a2e7d0256e63f66fe2682b

sna/dri2: Enable immediate buffer exchanges
The primary benefit of this is avoid the extra blit when using a
compositor and instead propagate the compositor flip on the frontbuffer
to the scanout, or equivalently allows a fullscreen game to flip onto
the scanout without intervention by TearFree.

I'm using the following:
i5-3340m
Linux-3.15.5
Mesa-10.2.4
Xorg-server-1.15.2
I'm not using a compositing window manager. I'm using Openbox or JWM.
I configured with:
# ./configure --prefix=/usr --libdir=/usr/lib64 --enable-kms-only
--with-default-accel=sna --enable-glamor</pre>
