Hi list.
I often use X11 forwarding to run Linux programs with GUI.
Recently I upgraded from vbox 4 to version
VirtualBox-5.0-5.0.16_105871_el6-1.x86_64.
(My Linux host is headless Rhel 6.7 Server with xorg-x11-xauth package
installed)
I noticed that when I type "VirtualBox" in shell and then close its
window the process remains running. Then I noticed that there's another
hidden window in taskbar.
I have to press Ctrl-C or close the second window to end the process.
This only happens when I connect from Windows and use cygwin xwin server
(but not xming or Linux client)
The visible window is captioned "Oracle VM VirtualBox Manager@hostname"
and the hidden one is captioned "VirtualBox@hostname"
It's not really hidden. There's a white pixel at the top-left edge of my
second monitor
I upgraded my Cygwin installation today, but the problem did't go away.
Before the upgrade I had some messages appear in XWin.0.log, but now
they're gone:
[656077.648] winMultiWindowXMsgProcErrorHandler - ERROR: BadWindow
(invalid Window parameter)
[656077.664] winMultiWindowXMsgProcErrorHandler - ERROR: BadWindow
(invalid Window parameter)
[656077.664] winMultiWindowXMsgProcErrorHandler - ERROR: BadWindow
(invalid Window parameter)
I start the server from shell using an alias:
alias runx='run xwin -multiwindow -noprimary'
I have this at the end of my ~/.ssh/config:
Host *
ForwardX11Trusted yes
ForwardX11 yes

Thanks for reporting this.
I tried to reproduce this issue with that VirtualBox RPM on a Centos 6.7
VM, without success.
It's not unusual for X clients to create 1x1 pixel windows which only
exist to receive events, but such windows are usually hidden by making
them InputOnly.
You could possibly explore this a bit using xwininfo, to determine if
this is a bug with VirtualBox (where the window isn't being correctly
marked as hidden) or XWin (where the window is being show, desipte the
fact it should be hidden)

Hi.
With recent Cygwin the problem became harder to reproduce: it only works
once. On subsequent launches of VirtualBox the extra window appears in
the taskbar for about a second and then closes. You have to restart X
server to see the bug again.
In the meantime I installed xwininfo. Beside "xwinclip" it shows 3 or 2
children of the root window.
xwininfo: Window id: 0x61 (the root window) (has no name)
Root window id: 0x61 (the root window) (has no name)
Parent window id: 0x0 (none)
4 children:
0x80000b "Oracle VM VirtualBox Manager": ("VirtualBox"
"VirtualBox") 770x550+8+30 +8+30
0x800002 "VirtualBox": ("VirtualBox" "VirtualBox")
1366x768+0+0 +0+0
0x800004 (has no name): () 1x1+0+0 +0+0
0x600001 "xwinclip": () 500x500+1+1 +1+1
Closing the window with right click on taskbar does not change the
number of windows, just changes Map State of "VirtualBox" from
IsViewable to IsUnMapped.
On second run there's no "VirtualBox" at all. I think it's the one that
disappears quickly.
Could it be some signed/unsigned thing with window id counter in the X
server?
