I added GALLIUM_DDEBUG=800 and checked using environ file that it is applied. Interestingly, I see no performance degradation (am I doing something wrong?). I have played XCOM for about 3 hours (which seems to be considerably longer than usual), then it got stuck. The screen got black for 10 seconds, then image returned, and I could move the mouse pointer, but do nothing else. I was able to switch to tty3, but when I switched back, it froze completely, and I had to use sysrq to reboot. The hang is visible in kernel messages, it is attached. There is no /home/$username/dd_dumps/ directory. I wonder whether the GALLIUM_DDEBUG variable is having any effect? Also, I can't find any documentation to it, the only thing I was able to find is this: <a href="https://patchwork.freedesktop.org/patch/57799/">https://patchwork.freedesktop.org/patch/57799/</a> Inspired by <a href="show_bug.cgi?id=80419#c66">comment 66</a>, I tried GALLIUM_DDEBUG=help (like "GALLIUM_DDEBUG=help glxgears"), but nothing is written to stdout. 01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc.
