Situation

You are using the xf86-video-intel driver and your X.org server shows black artifacts while scrolling in firefox or crashes when using Empathy. The xf86-video-intel X.org driver in 13.1 uses the newer SNA acceleration by default. If you experience this problem, you should switch to UXA acceleration.

Procedure

Open the file /etc/X11/xorg.conf.d/50-device.conf and add

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "AccelMethod"  "uxa"
EndSection
