             Bug #: 51809
           Summary: jReality "Export->Image" on nouveau corrupts memory /
                    locks up X server
    Classification: Unclassified
           Product: Mesa
           Version: unspecified
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: critical
          Priority: medium
         Component: Drivers/DRI/nouveau
        AssignedTo: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
        ReportedBy: luke.hutch-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org


The jReality viewer applet (e.g. run with "javaws
http://www3.math.tu-berlin.de/jreality/ws/jrealityApps/plateauProblemPlugins.jnlp")
manages to corrupt memory in the X server and/or hard lock up the X server if
you choose "File->Export->Image". The crash or corruption happens a few seconds
after you hit "Save", while the applet is performing off-screen GL rendering.
Sometimes junk is written to the X backing store, sometimes the desktop just
completely locks up. The machine still seems to be running, but even killing
Xorg remotely doesn't seem to return the display back to a text vterm.

Observed in both Fedora 16 and Fedora 17.
