Yep, that seems to have fixed the tearing! Thanks. At 
https://askubuntu.com/questions/418398/tear-free-disabled-in-intel-graphics-tearing-in-xubuntu 
it was suggested to use:

|Section "Device" Identifier "Intel Graphics" Driver "intel" Option 
"AccelMethod" "sna" Option "TearFree" "true" EndSection|


which is what I've put in for now.
