/wp-admin/users.php for example.Hamburger icon should not be visible in front of the menu.
Hamburger icon overlaps the My Sites menu.

Also, the hamburger icon overlaps the page content if there is no main heading on the page.
I haven't found this issue. However, I did fix the issue of the icon overlapping the Jetpack logo here

Thanks @eliorivero! I'm still able to reproduce this on Ubuntu 16.04 LTS and Chrome Version 57.0.2987.133 though (tried busting the cache too).
The previous description was not entirely correct since this only happens on tablet view size (in this case between 480px and 782px).

Fixes the problem for me!
