Spectacle + emacs full screen
I don't know if the following is relevant...
My emacs version is: 27.0.50, compiled from sources.
I use emacs in full screen mode namely with:
in my dot-emacs.
In fullscreen mode, I don't have access to the panel, where my Spectacle
And my purpose is to take a screenshot of emacs.
Also Spectacle is configured so that it doesn't show any dialogue window, but
instead goes directly to "select an area and then press enter; and then save
the image silently; and go away".
So I go on "konsole" (so I have access to the panel), then click on Spectacle,
then do "Alt-Tab".
First issue, I should be over emacs window, but it still shows me konsole
window. (I've got a thumbnails column of all my windows when doing Alt-Tab, so
I know I should be over emacs, but it doesn't show).
Then it tells me that I can press Escape, to leave.
But after doing so, it seems I have no mean to do actually anything anymore:
plasma session is inaccessible (Alt-tab, or moving the mouse the the upper-
left corner have no effect anymore; pressing "escape", or "enter" neither),
and I can't leave Spectacle.
Only solution I've found: go in another tty and do a killall spectacle.
And when I come back, emacs which was originally "divided in two", isn't
anymore, so it's been tampered during the operation.
I don't know if that would be reproducible with a debian's version of emacs.
