No, I believe it is unrelated to the old bug
<https://bugs.gnu.org/40493> when I changed kmscon, since

- this affects the layout switch at the start of the installer or
  when pressing F1 (Alt+Shift is unrelated, I should not have
  mentioned it),

- reverting Ludo’s fix d904abe0768 to the original bug makes layout
  selection work again (but causes the original bug 100% CPU usage)

- German keyboard layout is affected too, even though it does not use
  Alt+Shift toggleing, and

- apparently even with Ludo’s d904abe0768 the layout switch from the
  start of the installer can still be triggered somehow, since
  keyboard layout eventually switched to Amharic, but I don’t know how
  I triggered it last time.

Regards,
Florian
