With Enlightenment 0.25, gtk3 builds of emacs stop updating the screen
after switching virtual desktops away.  They still respond to input.
Display updates can be restored by iconifying or shading (aka rolling
up) the window.

(If you iconify, virtual desktop flipping is fixed until the window is
shaded.)

Enlightenment 0.25 started setting _NET_WM_STATE to _NET_WM_STATE_HIDDEN
when switching virtual desktops.  Previous versions of Enlightement did
not do this.

Xaw builds are not affected.  I've reproduced with 27.1 from debian
bullseye and git master.

Steps:
1. install enlightenment 0.25 and start a session
2. add at least one virtual desktop (Settings > Screen > Virtual
Desktops)
3. start a gtk3 build of emacs
4. switch to a different virtual desktop and back.  Typing should not
cause the screen to update.  But C-x C-c will exit.
5. shade the window and unshade (double click the title bar twice).
This should restore normal input.


Thanks,
Ross

This was a month ago, but there was no response to this message, so I'm
assuming that Martin's change fixed this, and I'm closing this bug
report.  If it's still a problem in Emacs 28, please respond to the
debbugs address and we'll reopen.
