> Under the Enlightenmnet window manager 0.25, emacs w/GTK3 stops updating
> after switching to a different virtual desktop and back. It still
> responds to keyboard input. It can be restored by shading (aka rolling
> up) or minimizing the window.
>
> Further, minimizing the window will cause emacs to behave correctly
> after future virtual desktop switches. At least until another unshading
> - at which point it stops updating again.
>
> Enlightenment 0.25 began setting _NET_WM_STATE to _NET_WM_STATE_HIDDEN
> when switching virtual desktops. According to xprop, the value is
> cleared after returning to the emacs desktop.

> To reproduce:
> 1. install enlightenment 0.25 and start an X session
> 2. configure at least two virtual desktops in Settings -> Screen ->
> Virtual Desktops
> 3. install emacs using the GTK3 toolkit and start it
> 4. switch to another virtual desktop and back
> 5. focus the emacs frame, typing will not show up, but keyboard
> shortcuts still work (C-x C-c is easy to verify with)
> 6. double click the window title bar twice to shade & unshade. The

Thanks for the report. I suppose this is the problem described in
Bug#49955 28.0.50; Emacs got quasi freeze. For some reasons, Masaru
Nomiya reported that bug as fixed but we never got a conclusive answer.
Also the problem he reported here
https://www.mail-archive.com/enlightenment-users@lists.sourceforge.net/msg26981.html
apparently had no conclusive outcome either.
Can you try commenting in the two lines
/** SET_FRAME_VISIBLE (f, 1); **/
/** SET_FRAME_ICONIFIED (f, false); **/
in xterm.c and tell whether that solves the problem. If so, we could
add an option to set these in accordance with the window manager used.
Thanks, martin
