cc: Make the invalidation frequency buffer bigger.

With large enough tiles we can get visible checkerboards if the buffer
we use for invalidation frequency is too small. Note that this fix
is a work around to make this case less likely to hit.

The proper fix is to stop repainting off screen frequently invalidating
content at a higher level.
