Thanks for the clue. I get:
(mapcar (lambda (f) (frame-parameter f 'visibility)) (frame-list))
=> (icon icon t)df
Whichever frame I've forced to be "live" always gets t, and the others
become icons.
If I split the screen to show two frames side-by-side, they both become
visible.
I haven't changed anything in my window manager config, and the i3
package hasn't been updated since August. The only recent commit that
looks like it could be at all relevant is 2c0cd90083.
Hope this points the way further...
