Static Menu flickers on IE11

I use Ultima with a static left menu, and noticed that in IE11 the "menu collapse/expand effect" is triggered on each and every page navigation. This leads to a lot of flickering, e.g. the following effects are always triggered:
  • Left menu slide-in (transition: margin-left 0.3s)
  • Menu-Button flipping
You can easily reproduce it with the ultima showcase, using IE11. It doesn't happen on Edge, neither on Chrome or Firefox.

Could you have a look into that? It would be very nice to make the application less twitchy on IE11.
Thanks,
Jörg.

Could you please try it after adding the following css?

Code: Select all

.layout-wrapper .layout-menu {
   margin-left: 0;
}

Unfortunately, that doesn't change anything. Still flickering.
What I noticed is that it's fine as soon as I start the dev tools (F12).

I think it is an IE11 bug. Unfortunately, I still didn't find a solution. I'll try the other CSS tricks for IE11.
