Initially it's totally unwatchable but slowly comes back as it warms up, getting less and less "jaggy".

This is uncanny. Mine has been doing exactly the same recently but I also have a problem where the bezel is a little loose, when I clicked it back in place it also made the screen was normal again. Perhaps it is a contact problem which is exacerbated by the cold.
