I see your point, but in practice, specially in embedded systems, the "larger
virtual desktop" premise is not valid. BlackBerry phones have an extra HDMI
port apart from their own display that behaves idependently. Also, the way I
came accross this bug was on an embedded system with two independent screens.
I just wanted to let you know the context.

So maybe we should go the documentation way?

Thanks,
