Steps to reproduce the problem:
1. Open tab. Navigate to any website
2. Open another tab. Navigate to any website
3. There is a good chance, on switching to the first tab the problem occurs

What is the expected behavior?
Normal switching to tab.

What went wrong?
On switching to tab, often (like one in four times) the omnibar "candidate list" opens and stays open until you click on the url, or use F6 to focus the url and press escape to close the list again. As the list overlays a good amount of the viewport it is very annoying.

Did this work before? Yes Don't now the version. Began a couple of days ago.

Chrome version: 62.0.3198.0  Channel: dev

Could be a chrome os problem as well.
