I searched for similar bug reports and here are my findings:

* Bug 479852
* Bug 480806
* Bug 425234
* Bug 426388

And here's another easy way to reproduce the problem:

1) Load your mailbox in Google Mail
2) Full-zoom to 200%
3) Enable the 'Tasks' labs feature
4) Login again to your GMail account with the 'Tasks' labs feature enabled.
5) Scroll now becomes seriously slow.
