I will  try and remember  this. The issue  is, though, that  because the
problem occurs only as infrequently as it does, I can't guarantee that I
will remember doing it every time, I switch workspaces. Because over the
course of a couple of weeks, I switch workspaces hundreds of times easi-
ly without anything ever going wrong. :)

I usually  have Emacs as a  mostly full-screen window with  small status
bars above and below it.

It's XMonad¹ — which is one of those tiling window managers that are not
re-parenting window managers².

Can do! Do you want me to try this right away or give the "move the
mouse pointer off of the window" routine a shot for a while first?
