https://bugs.freedesktop.org/show_bug.cgi?id=37193 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@xxxxxxxxxxxxxxxxxxxxx ReportedBy: info@xxxxxxxxxx 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 wouldnât 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.
