Comment # 1 on bug 83022 from Michel Dänzer

First of all, please attach /var/log/Xorg.0.log and the output of dmesg and
glxinfo.

The output from running the app with valgrind --leak-check=full (preferably
with debugging symbols available for r600_dri.so) should be a good start to
identify where the leaks are coming from.
