Don't know if it's just me, but the OSM maps seem extremely laggy to the extent it's basically unusable. On the MacBook the airline summary page is exceptionally slow and navigating the new route map is impossible. Meanwhile I also tried it on the iPhone and it consistently reloads the page whenever you attempt to interact with the route map.
It's laggy, sometimes it doesn't load at all, and if it does I get giant white squares on parts of my screen when I try to click on something, just like DL727. Not just on the map either. Everything clickable on the screen is affected.
Switching to GCM doesn't help either as that just gives me an error message.
