Hi. Currently, after switching persps, the buffer before the switch is still set as
(current-buffer), so thepost-command-hookis ran for that buffer with the new buffer as the(window-buffer). This can cause untold horrors like in: magit/magit#5098. And the Emacs maintainers have declared this behavior in a command to be a bug in:https://debbugs.gnu.org/cgi/bugreport.cgi?bug=69259.
