I have an intermittent problem where a GUI emacs frame disappears. The
trigger for this is seeminly random and has varied between

- - moving the mouse completely unrelated to the emacs frame
- - moving X focus outside emacs
- - moving X focus inside emacs
- - clicking the menu-bar
- - moving the mouse outside the GUI frame

The frame disappears and neither it or its window decorations are drawn.
The X window is still listed as existing, it is still in the task bar
and I can query it with wmctrl.  Additionally, I can toggle the the X
window's minimization/maximization.  When i maximize it through
interaction with the taskbar, I can see that the emacs frame is drawn
momentarily and then disappears again.  It is so momentary that I often
only see a flash on the screen but ocassionaly can see some of the emacs
frame for a split second.

When X windows indicates the emacs frame is
"visible" and has focus, I can interact with the frame.  For example, if
the disapearing frame was an emacsclient, I can connect another
emacsclient to the daemon and interact with the frame.  If I give the
invisible frame X focus and type into it, I can see in the other frame
that keypresses and mouseclicks into the invisible frame behave as if
the frame were visisble.  From emacs and X perspectives the frame is
there, it is just not being drawn.

I have also posted this issue at
http://emacs.stackexchange.com/questions/14005/emacs-frame-disappearing
where a few people have indicated it happens to them.  I experience this
on Gentoo Linux with the awesomewm window manager, someone else is
experiencing it on Redhat with the Gnome DE.  Yet another experiences
this on Mac OS X (though they did not specify if it was the X11 or not).

The trigger to reproduce this for me is:

- - create a GUI frame by any method (with or without -Q option)
- - work normally for some period of time between minutes and weeks
- - observe a disappearing frame.

bug#21775: Updates to bug 21775

[Casey Webster]

[-- Attachment #1: Type: text/plain, Size: 889 bytes --]

I have recently converted my workflow to use an emacs daemon and all of my
other sessions as client frames of that daemon.  This has let me gather
some more insight into this bug.

I still occasionally observe a GUI frame disappearing and exhibiting the
documented behavior.  I can close this client frame and start a new one and
the new one will immediately disappear, reproducible 100% when in this
state.  If I start a terminal frame however and then start a GUI frame the
behavior of emacs is returned to normal (for a while anyway).

This suggests to me that this is not a window manager issue since it
persists across emacsclient processes and this is either a problem with gtk
or with emacs.  If anyone has any insight into data I can collect to better
define the problem, please reach out to me.  This happens often enough that
I could collect any needed data within a day or two.

(I'm going through old bug reports that unfortunately got no response at
the time.)

This was five years ago -- are you still seeing this problem in more
recent Emacs versions?

More information was requested, but no response was given within a
month, so I'm closing this bug report.  If the problem still exists,
please respond to this email and we'll reopen the bug report.
