           Summary: [945GM SNA] rotation related issue (regression,
                    bisected)
        QA Contact: intel-gfx-bugs at lists.freedesktop.org
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: spamthis at freenet.de
          Hardware: x86 (IA32)
            Status: NEW
           Version: git
         Component: Driver/intel
           Product: xorg

When using i3lock (http://i3wm.org/i3lock/) and intel-video SNA (currently
2.99.914) in rotated setup i3lock does not cover the whole rotated screen so
parts of the desktop are visible. The black striped yellow background in the
attached screenshot should not be visible as it is the desktop background image
and occours at 1024 pixels. This problem does not occour with UXA.
