Illustrator Gradient Glitch

[gary_brown]

I've created a graphic comprising of three concentric circles, each with it's own colour gradient tint.

When I zoom in closely there are, what look like, fragments of solid colour at the edges of the gradient - image inserted for reference. Why is this and can I get rid of it?

Help much appreciated - thanks in advance.

Probably a Preview problem. Try Cmd E or Ctrl E to switch between GPU and CPU preview and see if the problem goes away.
