VirtuaWin (http://virtuawin.sourceforge.net/) is a virtual desktop
manager for Windows that lets you switch between several "virtual
desktops", similar to those provided in KDE& Gnome.
When switching between desktops that have CygwinX windows open,
occasionally the Xserver draws to the wrong window. This is difficult
to describe, so will continue with an example:
I'm afraid I think this falls into the category of "known problems", see [1].
The tricks that XWin uses to implement multiwindow mode don't seem to be
compatible with the tricks that VirtuaWin uses to implement multiple desktops.
[1] https://bugs.freedesktop.org/show_bug.cgi?id=21540
Using Windows 7, Cygwin/X v1.8.0
Steps to reproduce:
1) Install VirtuaWin from http://virtuawin.sourceforge.net/
2) Start the CygwinX server
3) Open a (DOS) cygwin window
4) Type "xterm&" twice, to open two xterm windows. Maximise these two
windows to full screen.
5) Move one of these windows to desktop2
6) Type "ping google.com -n 1000" to get a stream of data appearing in
the xterm window on desktop2
7) Go back to desktop1, and make sure the DOS cygwin window is selected
8) Switch back to desktop2. The "ping" xterm window should be selected.
9) Switch back to desktop1. The cygwin window should be selected.
What should happen:
The empty xterm session on desktop1 should be displayed in the window
behind the cygwin window
What happens:
The ping data stream appears in the xterm window on desktop1, and
continues receiving updates every second.
Selecting the xterm window causes the ping data to disappear and the
empty xterm session to be displayed correctly.
This is reproducible every time. The critical thing is that if the
xterm window on desktop1 is not selected after a desktop switch, it
shows the data from the xterm window on desktop 2.
FWIW, this problem doesn't exist with xming, and I haven't seen the
issue with any other applications.
Xming version number, please?
Is there anything else I can do to help debug this? Unfortunately it
is necessary to install VirtuaWin to reproduce the issue, but it's
very reproducible.
