I have installed opensuse 13.2 on a laptop with Intel i5 CPU and 5500 GPU.
The GPU uses a driver from Intel (called i915 or intel) which is apparently defective. The windows sometimes show content distorted, and video from a webcam is not shown correctly. Attempt to show video from webcam can crash the OS.
I searched for answer in Internet. There was a good one in Ubuntu forums: http://ubuntuforums.org/showthread.php?t=2208072
As it appears, Intel has changed the graphics acceleration method from UXA to SNA. But they didn’t manage to do it correctly.
Bringing back to UXA solves the problem. For that, a xorg.conf file must be created. I put it in /etc/X11/xorg.conf.d/ The name of the file is 20-intel.conf and its content is
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "uxa"
EndSection
I am a bit surprised that this worked, because the driver was i915, not intel.

If this is a need for a bug, you’ll want to submit it to
bugzilla.opensuse.org - include details about the hardware and release in
your bug report along with your workaround/fix.

i915 is the kernel module, intel is the Xorg driver.
No.
There’s bugzilla.opensuse.org, bugzilla.novell.com, and bugzilla.suse.com.
But the only difference is the appearance/theme…
