This driver uses SNA as the default acceleration method. You can try falling back to UXA if you run into trouble. To do so, save a file with the following content as /etc/X11/xorg.conf.d/20-intel.conf:
1 2 3 4 5 6 Section "Device" Identifier "Intel Graphics" Driver "intel" Option "AccelMethod" "uxa" #Option "AccelMethod" "sna" EndSection
