<pre>Can you addr2line -e /usr/lib/xorg/modules/drivers/intel_drv.so -i
0x7fe46b3c6e22 ? I think it implies that DamageRegion(sna->mode.shadow_damage)
is itself NULL. That address locally is RegionNotEmpty(), which we rely on in
many many places so is unlikely to be the culprit rather a victim. Still worth
./configure --enable-debug to catch such errors earlier.</pre>
