Does this affect all hardware or only some hardware? When I try to
reproduce the bug with
for t in `seq 1 10`; do eog /usr/share/backgrounds ; echo `grep
"object bytes" /sys/kernel/debug/dri/0/gem_objects` `ps ocomm,vsz,rss
1020|grep X`; done
I get
grep: /sys/kernel/debug/dri/0/gem_objects: No such file or directory
