Description: xf86-video-intel 2.99.917-5 glitches with
broadwell video chips
Additional info: * package version(s): extra/xf86-video-intel 2.99.917-5 (xorg-drivers xorg) * config and/or log files etc. Steps to reproduce: On nearly any laptop with a broadwell video chip, (intel 5500, or the like), such as the Thinkpad Carbon X1 Gen3, or the latest generation Dell XPS 13, simply start up dosbox or "mplayer -vo xv" or pretty much anything with XV video output, and you will experience corruption, green lines, distortion, etc |
This task depends upon
https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1432194
EDIT: seems there's a few possible bugs that might have some overlap in terms of reports, so that thread may not be as useful as I thought, the below poster seems to have found the correct bug.
this can be worked around by using xf86-video-intel-git, but given that broadwell CPU laptops are going to be more and more common this should likely get fixed in the stable release.
And this the patch that needs to be backported (do we backport patches in Arch?): http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/commit/?id=c43617b739e358064396912c7a7a8028ca91d201
EDIT: Might be the result of a new bug upstream: https://bugs.freedesktop.org/show_bug.cgi?id=90978
Please test with xf86-video-intel-2.99.917.20150616 in testing
