I'm sure you're aware of this - but asking anyway.
Have an issue continuously panning the x axis on a map view.
If I add a graphic to a graphics layer then pan all the way around the world back to the position where the graphic should be, it's no longer displayed.
Also if I place one graphic on one side of the international date line and then another on the other side, one of the graphics doesn't appear when it should until I pan all the way around the globe to the where it then appears and the other one doesn't.
See this plunkr for a demo:
Also calling normalize() on an extent isn't working as expected - I know it's not in the official api, but there is a public method on the object still - guessing this is also related.
SceneView appears to be fine.
