            Bug ID: 102315
           Summary: GPU Hang when replaying API trace of lightsmark
           Product: Mesa
           Version: 17.2
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Mesa core
          Assignee: mesa-dev at lists.freedesktop.org
          Reporter: jason at jlekstrand.net
        QA Contact: mesa-dev at lists.freedesktop.org

While trying to debug a perf issue in lightsmark, I took an apitrace and, when
replaying it saw GPU hangs on release builds and assertion failures on debug
builds.  The assertion failure was because we tried rendering to render to
something that that clearly isn't renderable (it was DXT3) and it looks like it
was hidden because it was inside of a display list.  Trace can be found here:
