bug#44180: 28.0.50; Emacs frames won't redisplay unless resized

Can you please describe this in more detail.  As I understand it, your
initial frame looks as usual until you do C-x 5 2.  At that moment, the
initial frame becomes non-focused and appears as a stacked title bar
while the new frame becomes focused and appears as expected.  Is that
right?  Then how does the "fullscreen frames by default" fit into this
picture and how does a tiling manager use stacking?

Maybe we need an option for 2c0cd90083.  Maybe we also should just
wait.  I'd expect a few more of such reports to drop in.
