Chrome Version: Versión 60.0.3112.114 (Build oficial) (64 bits)
Chrome OS Version: 9592.96.0 (Official Build) stable-channel lulu
Chrome OS Platform: Chromebook 13 (7310) i3

Steps To Reproduce:
(1) Open a new tab
(2) Search something on Google
(3) Enter any site
(4) two finger horizontal swipe to the left to go back
(5) two finger horizontal swipe to the right to go forward 

Expected Result:
Go forward

Actual Result:
If you do exactly the two finger swipe right (meaning that the cursor did not move, but the page did) the page should be still black and white until you move the cursor.

How frequently does this problem reproduce? 
Always. Sometimes you have to play around with the horizontal swipe to pull  it.

What is the impact to the user, and is there a workaround?
You get stuck at the black and white page and loose the flow of navigation. 
The workaround is to do a 2 finger swipe and then move the cursor.

Really don't know if this behavior was intended, but is frustrating for UX.
