Very high cpu usage when moving the cursor

[N-R-K]

Hi,

I see my cpu constantly staying at ~50% and spiking to ~60% on occasion when moving the cursor around with xcolor. Don't believe such high cpu usage should be necessary for whats being done.

Simple magnification shouldn't be such a hassle but for now lessning the update rate when moving the cursor would work for me.
