Xorg old log
[Just a side note: I am filling this for second time since this bug can take
whole xserver down if reproduced for second time]

2) System environment:

3) Reproduce steps.
mpv -vo=opengl <anyvideo>.mp4
seek there and back and wait a while
VO: [opengl] 1920x1080 => 1920x1080 yuv420p
Failed to open BO for returned DRI2 buffer (1920x1200, dri2 back buffer, named
3).
This is likely a bug in the X Server that will lead to a crash soon.
Program received signal SIGSEGV, Segmentation fault.
0x00007fffdb3922c2 in ?? () from /usr/lib/x86_64-linux-gnu/dri/i965_dri.so
This usually takes gnome-shell down as well just after the crash
(but running mpv under gdb saves the gnome-shell):

If this bug is triggered for a second time it takes whole gnome down (only the
Logout screen appears)
