I see this too, also on OS X. Some sites seem to suffer worse than others, but the overall behaviour seems to be:

- scrolling "past" the end of the scroll area makes the scrollbar size change (as if the scroll area was much bigger)
- mouse cursor position seems to become offset by the amount of "overshoot" caused by the phantom scrolling
- scrolling to the opposite end can somewhat reset the oversized scroll area, but it will again overshoot (in the other direction)

Same behaviour on horizontal scrolling; then the cursor offset is horizontal. Keyboard focus works as expected.

I caught this one too.

Just wanted to add that it only refers to the click event, as if the mouse is displaced but you try to make the zoom gesture, it will zoom to the real mouse position.

Also happening to me on OSX.

Also happening to me: OSX

Same here on OSX

Also happens to me on OSX.  Any mouseover events are also displaced.  Ending the tab's process in Chrome Task Manager then reloading the tab fixes it temporarily.

Me too on OSX. I can get it to happen pretty quickly on github, dont have steps though.  You can tell where the page thinks the click is by right clicking. What I was able to temporarily work around this by closing the tab and opening it back up and then navigating to whatever page but it will happen again soon after...

This appears to be a duplicate of https://bugs.chromium.org/p/chromium/issues/detail?id=639046, which has a fix up for review.
