iCloud scrolling issue and Zoom in Chrome
At one point, I was squinting at the screen to read something small when I decided to Zoom-in and lo and behold, the scrolling stopped!
Turns out, if you zoom out in Chrome, iCloud will display this page scrolling issue. It doesn't happen at 100% zoom, or if you Zoom-in at a higher than 100% level.
So, if you are facing a scrolling issue in Chrome and iCloud, simply set your zoom level back to 100% and get on with your work!
