The essence of the problem is that if you hover on some element on the page to which the transform: spelled, then the fixed menu jumps 1px down then, after 0.5 seconds, it becomes back 1px up.

At the same time, no element changes its properties of width \ height \ indents.

Filled code: jsfiddle menu

Because I am writing to Sass, copied compiled css. How to reproduce the error? It does not always appear, so that the menu starts to jump, you have to squander it to the very top, so that the fixed disappears, then turn it down and point at the blocks. If everything is fine from the first time - it is necessary to do it again, usually it works one time. This code is better to download and open in chrome. Jsfiddle does not reproduce the error (I would like to know why). Put the prefixes - the result is the same. Firefox works correctly

Also video recorded: dropbox video attention to the red bar on top

A long time ago I came across this problem, I asked a lot of people, I never received an answer ...

    Che is nothing clear on this video, can you remove it not with a mobile phone, but with some screen-capture? Well, in my Chrome, there are no unnecessary movements when you hover over this block. - Sasha Omelchenko
