This happens for all layers. It depends on the number of tiles you have 
shown. The WMS plugin needs to learn some buffering to speed up work. 
Currently it seems the stuff is recomputed and redrawn for every action.

But only redrawing is really required. The clipping, rescaling, cropping 
and so on is only necessary when zoom or view changes.
