Hi, I'm trying to get a stable way to use my video card. When disabling DRI (adding Option "DRI" "false" to xorg.conf, I can trigger an X crash when running two instances of: /usr/share/vtk/Rendering/Python/assembly.py which is a sample programm from the package "python-vtk" on Ubuntu. the X crash occurs this way : 1- make the windows overlap 2- move one of the two windows so that rendering is triggered on the other window. I already had such problems, but it was my fault. I hope (and think) that this time I did nothing bad. I join my xorg.conf, xorg log and a gdb backtrace of X.
Created attachment 11861 [details] xorg.conf
Created attachment 11862 [details] Xorg log
Created attachment 11863 [details] gdb backtrace
looks like a mesa bug.
Is this still an issue with current Mesa git?
No response. Closing.
