Have you got a 'change-range' node plugged into the displacement? You could
ramp up the max just to see if it's having any effect.
Also, recently we've been having problems with the displacement-max value. It's
normaly set to 2, but we've been setting it much higher, like 10, just to avoid
some nasty glitches. Might be worth a try.
