Comment # 9 on bug 1001473 from Dominique Leuenberger

I have since a 'more modern setup' - with one 4k screen and one fullhd screen.

kernel 
           Device-2: Chicony HP HD Webcam type: USB driver: uvcvideo 
           Display: wayland server: X.Org 1.20.8 driver: intel unloaded:

and I just recorded successfully recorder a (sort) screencast video with this
setup

Using TW 20200622

Of course, it worked on my systemd before - but at last I now also have a
dualscreen/different dpi screen setup.

Can you verify if this issue is also fixed for you please?
