Steps to reproduce the problem:
1. Set chrome://flags/#top-chrome-md to "Refresh"
2. Maximize the window

What is the expected behavior?
There are round edges on each side of the tabs, and the "+" sign at the left of all tabs is situated in the middle, vertically.

What went wrong?
It looks like the topmost pixels are not displayed. As a result the tabs do not show round edges, all texts in the tab and the "+" have more spaces below than above them.

See pictures of maximized windows and non-maximized windows, also aligned to the top.

Did this work before? N/A
