Comment 10 for bug 105836

This problem doesn't show up in the window with the list of screensavers to the left - it only happens when you click the the preview button and it shows you a fullscreen preview of the "blank" screensaver. The area in the window from which you can see a list of screensavers is always black.

On the off chance I waited a good three minutes with the vesa driver when the fullscreen preview was exhibiting the problem but the grey did not go away.
