Put some water on it.

Update: Looks like it fixes itself after a little bit. I'm wondering if Hover Zoom is to blame as it was on in incognito for me but I can't reproduce now so I don't know...

OS X 10.10

Chrome 41.0.2272.89 (64-bit)

It's happening to me as well. I thought it may be Privacy Badger blocking some JS or something stupid like that but after trying in incognito mode I can confirm it's probably not a plugin causing it (The plugins still being loading in incognito mode are: 1Pass, EditThisCookie, HoverZoom, JsonView, and RES). In Chrome Canary (43.0.2330.4 and 43.0.2331.0 tested) scrolling seems to work fine. It also works fine in FF (34.0.5 and 36.0.1).

Hmm. What OS?

Works for me (Chrome 41.0.2272.89, OS X 10.9.5)
