Strange disappearing xterm behaviour (recent) - Xwin multi window

Strange disappearing xterm behaviour (recent) - Xwin multi window

[Gulliver Smith]

I have been running a cygwin X server in multi window mode for years,
first supporting xterms running on external boxes, then in a variety
of VirtualBox virtual machines. X is started as follows on both
Windows 10 and Windows 7 boxes.

       /usr/bin/X -multiwindow -listen tcp

I keep Cygwin up-to-date regularly, also my Linux virtual machines and
the windows hosts.

In the last few weeks I am getting new, annoying behavior.

Essentially, my X clients, e.g. xterm are no longer visible. A "ps" on
the linux VM shows that they are still running. This happens with
emacs too, and emacsclient calls also do not open windows on the
display.

Is it a change to Cygwin or a change to a Fedora 27 package? Is there a fix?

Thanks
Gulliver

Did the update of something cause this?

I don't see any other reports of anything like this.

It might be worth investigating what state the windows which have 
disappeared are in.  Are the X windows in a viewable or notviewable 
state, according to xwininfo?  You could use spy++/winspector/etc to see 
if a Windows window exists and is hidden or not.

Is this linked to any 'virtual desktop' type software?
