It's a real shame chrome moved away from GTK. Aura is probably fine for many use cases but it does weird stuff on multi-monitor setups (drawing artifacts and windows jumping around).
Aura really doesn't like my xmonad setup. Chrome doesn't like it at all either. If I lose focus of the chrome window due to a Panel coming up (undocked window), chrome won't regain focus and I can't type anywhere and I have to SIGTERM it to make it work again. quite annoying.
As an i3wm user, sometimes, but not always, after resuming from sleep, chrome puts context menues (and only context menues) on my other screen, so I wholeheartedly agree that Aura and multi-monitor (tiling?) setups have some issues.
