Hello there Peter,
I have a situation and I am interested to know your point of view, I suppose that you’ve already dealt with this.
-The Push side menu, at open/close is jiggling I have no idea why (tested in Chrome latest version);
-Also in IE11 latest version, the site wrapper, remain fixed is not moving being “pushed” by the menu.
I’ve read 2 subjects but I’m not so sure if we are talking about the same scenario.

Anyway, here is the link.
Please watch the right side of the yellow menu container in order to see the jiggling unwanted effect (in Chrome), for the second case, is obvious (in IE11).
If you need more details please don’t hesitate.
Thanks,
