screennsaver preview in sys prefs

[tonywalker23]

has anyone else notced this:

when i open sys prefs and go the screensavers section i see the little preview box to the right. when i select the space pictures screensaver it shows up in hte little preview box. but whats weird is on the little preview the stars seem to twinkle?!

but when the screensaver actually starts its just pictures moving back and forth and fading in and out.

any thoughts?

They twinkle due to the Ken Burns effect zooming the pics and the preview being so small. But yes, they do appear to twinkle
