I got no problems. Try this: add "i915.semaphores=1" to your kernel
options in /etc/default/grub (AND run update-grub AND reboot). E.g:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash elevator=noop
i915.semaphores=1"
I also do created /usr/share/X11/xorg.conf.d/20-intel.conf with this in it:
Section "Device"
Identifier "Intel"
Driver "intel"
Option "AccelMethod" "exa"
Option "MigrationHeuristic" "greedy"
Option "DebugWait" "true"
Option "SwapbuffersWait" "false"
EndSection
^ ^ again, reboot if you do that and/or play with those options.
YMMV.
