Hmm..do you see little spiders crawling all over you?

i have the same problem. had it for awhile now

I think there is a setting that will fix it, but it will cause bigger problems.

Eric, do you remember it like that too?

Now that you mention it, @eric3579 reported that a week or two ago. I've since noticed it as well, but haven't the foggiest as to what's causing it.

There have been no changes around the time it apparently started, especially not anything that would cause such weird behavior.

It doesn't seem to happen all the time. (I'm trying to force it right now and nothing's happening.) And the image doesn't seem to be shifting in its DOM attributes, so it seems like a weird browser bug (?) only in Chrome (?).

same on Chrome on Win7 64bit. noticed it a few days ago.

Sometimes.

Chrome (latest) on XP and it's been doing it for me for ages!
If you mouse over/off the title text (link) of the video it moves a pixel each time.
Great fun getting the video thumbnails to "race" each other down the page but I don't quite think that's what you had in mind!

Looks like there's a couple of listeners attached to the mouseover in the CSS styles used for those items, in chartbeat.js

I haven't looked too hard but it on first glance it looks like it's trying to replicate the onkeydown behaviour to scroll the page but is scrolling the image instead.
