Yes, although the background isn't strange: it's a small section of a
scenic wallpaper from my home country, I think you'd like it ;).

Yes, I no longer get a missing slider after
(set-scroll-bar-mode 'right).

Indeed, it's on my todo to report this properly (I also get a missing
menu bar sometimes with Lucid/GTK, but I only notice it when I'm in the
middle of something else in 'emacs -Q', because in my config I have all
of these elements disabled), but I need to study for my finals first.

Yes, in my config I have:

  (defun blc-delete-spare-frame (&optional frame force)
    "Delegate to `delete-frame' unless FRAME is alone in terminal."
    (unless (eq (next-frame) (selected-frame))
      (delete-frame frame force)))

  (setq-default frame-auto-hide-function #'blc-delete-spare-frame)

amongst various other settings and advice to elevate the citizenship
status of pop-up-frames.

Right, but thereafter any use of the minibuffer leaves the minibuffer
selected at the end, that is until I type C-x o again.

Anyway, I can no longer reproduce the recipe in the OP following:

Fix wrong handling of minibuffers when frames get iconified/made invisible

https://git.sv.gnu.org/cgit/emacs.git/commit/?id=c873d16af61ae9b956c6dd6d9e50ebad2bb7666e

So I'm merging this report with bug#47766.  As Gregory points out, the
related bug#48249 remains.

Thanks,
