           Summary: [sna] Occasional artifacts on window borders (theme
                    dependent)
        QA Contact: intel-gfx-bugs at lists.freedesktop.org
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: b3nmore at googlemail.com
          Hardware: Other
            Status: NEW
           Version: unspecified
         Component: Driver/intel
           Product: xorg

Using kernel 3.15 and the xorg intel driver 2.99.912 from a git build on
2014/06/11,  I still get sometimes artifacts on window borders (they show
stripes) when using xfwm4 and sna enabled (Originally reported on launchpad
with screenshots:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1171411).
Recently I found out, that it only happens with one specific theme
(greybird-compact of recent xubuntu versions) and not with a quite similar one
(greybird). xfwm4 decorates window borders by repeatedly drawing little xpms
(left-*.xpm, right-*.xpm, bottom-*.xpm). The problematic theme uses 2x2 or 2x1
pixel xpms whereas the other uses 1x1 pixel xpms for those decorations.

For now I just copied the corresponding 1x1 xpms to the greybird-compact theme,
which works around the issue, but I guess there should be a real fix.
