I'm not able to reproduce it currently
I've run into similar issues (meaning, I've seen on others' websites and created similar issues 
) involving interactions between various bits of css and js that accidentally compete to resize page elements. Usually only happens when the window size is juuuust right, css and/or js end up battling over what size things should be.
I'm unable to recreate the issue on this particular website.
If I see it again I'll try and grab the size of the window with js for reproduction
Vlad It happens when the window size is 1009px in width. I also have a height of 1003px, not sure if the height makes a difference.
It's unclear if this is an issue that can be fixed, or something all browsers have when being on the edge of a CSS breakpoint. I was able to replicate in Safari at 1038px, but Firefox did not have any shaking, even when I matched some of the breakpoints in the page's HTML.

Can you post to webkit.org as appears to be a webkit issue then
