Might be caused by zoom setting in Windows OS like 125%.

I did have my zoom setting set to 125%. When I changed it to 100% the scrollbar went away. I'll need to validate that this is the problem in all environments we have experienced this in.

Assuming the zoom setting is the issue, the question now is, is this considered a bug in chrome as it used to work with a zoom setting of 125% prior to the latest release?

Thank you for providing more feedback. Adding requester "vamshi.kommuri@techmahindra.com" to the cc list and removing "Needs-Feedback" label.
