When the switcher popup is displayed, and showing the thumbs of active windows,
the thumbs are static unless there is damage going on under the switcher.
For example, if I'm playing a video in mplayer and looking at the video
thumbnail in the switcher popup, the thumbnail will update in realtime if the
popup is displaying on top of the real video window. But if there is no other
window causing damage to the screen underneath the popup, then the video
thumbnail won't update. It will update briefly when you hit the switch-window
key, but will stop again if you just sit watching the popup.
It's most noticeable if only half of the video-playing thumb covers a
damage-producing window. Then, only the half on top of the damaging window updates.
Will attach a patch that fixes the problem, but not sure if it's right.

patch to trigger damage on switcher popup
Tries to fix the problem by regularly triggering damage on the popup window.
Fixed (probably in a more intelligent way) in CVS today. Tested and works fine
