            Bug ID: 88248
           Summary: Calling glClear while there is a while there is an
                    occlusion query in progress messes up the results
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/i965
          Assignee: idr at freedesktop.org
          Reporter: neil at linux.intel.com

If any meta operations are used while an occlusion query is in progress (such
as by calling glClear) then the results aren't saved and restored correctly so
the final value is wrong. I posted a patch for this a while ago and I'm opening
a bug so we don't forget about it.

There is also a piglit test for it which I pushed to master
