When opening the friends list avatars in desktop still deform themselves heavily when one is crouching/proning. Can you add a parameter we can rely on which tells if the menu is open? It will open a way to fix the issue desktop users are experiencing for a pretty long while now and allow to put the avatar into certain states.
While we, who are making locomotion controllers cannot fix every issue (like that offset menu as you can see in the screenshot), it would allow us to at least prevent the avatar from playing tetris with its limbs.
