This can't be the mozillazine or bugzilla problem, as both are the same
and both are due to a regression that appeared in 3.6. You're reporting
the bug on 3.5...

Try disabling smooth scrolling, it is known to be too slow on many
occasions. I think your bug can be merged with #404827.

Anyways, can you try the latest 4.0 beta release (instructions on
http://glandium.org/blog/?p=1032), it has what is called "Retained
layers" and that should make things better.
