Applied. I'm not entirely happy that we need to sacrifice one of the
overlay windows for this, but you're right, it's probably okay given
how little planes are used on a regular desktop.

We could always provide a module parameter to switch this on and off
if that's ever something we want.

Applied, thanks.
