Hi! Ever since this(*) commit, scrolling became much slower and choppier on Google Chrome on my Ivybridge GT1 (Asus X301 laptop, Celeron 1007U). Additionally, graphics corruption can be seen while scrolling. Screenshot attached (top of the page and scroll bar).

The answer is probably update your kernel, but please attach your Xorg.0.log anyway.

The kernel is buggy (current 4.0-rcX), there is a patch heading upstream via drm-intel-fixes.
