           Summary: Crash while switching between OpenGL window and other
                    window
           Product: Mesa
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: critical
          Priority: medium
         Component: Drivers/Gallium/r600
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: info@noctus.net


Thanks to the Unigine Heaven demo I was finally able to reliably reproduce an
issue which I only experienced with Mplayer before.

Upon switching back and forth between one window where OpenGL is used and
another one, quickly the whole input and output of X freezes followed by a hard
restart of my system a few moments later.

Conditions to reproduce here:


1) Have the Composite extension enabled
   - the crash does not occur without the Composite extension
   - disabling Compositing in my WM (Xfwm4, uses XRender) does prevent the
crashes

2) Have rencer acceleration enabled
   - Setting RenderAccel to "Off" prevents the crashes
   - Crashes occur both with EXA as well as XAA

3) Start an application which opens an OpenGL context with a least amount of
complexity wrt the graphics
   - Crash is reproducible with Mplayer using the GL video output
   - Also reproducible with the Unigine Heaven demo
   - Not reproducible with glxgears (seemingly too simple)

4) Open another application window and start switching back and forth between
those two


Due to the hard restart I am currently unable to find any traces of debugging
information so help for getting started on this is greatly appreciated.

I am aware that there are quite a few other reports which sound similar to this
one and I thought about adding a comment on these. However, without any
additional info to add, my comment wouldn’t be that much worth. Thus I am
mostly hoping for help on gathering as much information as possible.

Aside from using the latest Mesa git master I am also using the latest git
master of the xf86-video-ati DDX.

(I also wanted to spare you from this lengthy message in #dri-devel ;-) )
