Hey Jonas,
I’ve made a more generic update, with the action performed via the jQuery piece that controls the fixed header animations, yet wouldn’t say it’s much smoother than your solution; the only difference is that this one can go with a logo of any size.
Regarding the issue with the logo in Safari on retina devices: I will need to test it separately, since I don’t have an Apple device at hand right now. Thank you for bringing this up!
Sincerely,
