Noise node very slow?


Is anyone having trouble with the noise node being extremely slow? I’m using it for grainmatching, so my node tree has three different noise nodes, one for each color channel, a blur node for each channel, shuffles to merge the different noise channels and not much else.

In comps where I have this, the noise nodes seem to occasionally take forever to render. I just had the comp stuck rendering three noise nodes for several minutes! I often also get the warning that a render is stuck, and it specifically says the node stuck is noise. Am I alone with this?
