When zooming out with the latest as of 2010-01-12, if I have an image on the screen, I get some white grid lines during the fuzzy portion of the zoom.

Example: http://www.flickr.com/photos/madhava_work/4269688214/
another: http://www.flickr.com/photos/madhava_work/4269759016/in/photostream/
Yep, here's a steps to reproduce:

1. Go to www.slashdot.org/
2. Double-tap on the title of an entry there to zoom in
3. Double-tap again on the screen

Actual Results:
White grid lines will show up after the initial zoom out and before the rest of the tiles are updated.

I like this patch a lot better.  The downside is it adds another canvas.

a third option which doesn't require the second canvas but only fixes us for zooming in (which is the case where the lines are more obvious due to them being bigger).

I'm not seeing this anymore and I can't find a bug about this being fixed. Mark or Matt, would you have any idea if we have one? If not, we can move this to WFM.

This is more an invalid bug rather than fixed because bug 437957 changed the approach entirely.
