Might have to do with finding fixed positioned elements.

It looks like setting `backface-visibility: hidden` does the trick. I've confirmed this only for chrome, using the [fps-counter](http://www.thechromesource.com/how-to-activate-the-frames-per-second-counter-in-google-chrome/). ``` .3d-accelerate { backface-visibility: hidden; -webkit-backface-visibility: hidden; } ``` The FPS counter...

Unfortunately that's not supported by my offcanvas plugin. You can try to implement the [codrop menu](http://tympanus.net/codrops/2013/08/13/multi-level-push-menu/). Though beware that solutions from codrops tutorials tend to break easily.

@Bervit Multi level slight menu's are doable, imply play around the `width` and `z-position`. It's probably still not ideal.

We will not implement this feature ourselves but will accept a PR.
