--nowgl and  LIBGL_ALWAYS_INDIRECT='' for VcXsrv,
plot(1:10) => plot appears on qt toolkit on cygwin octave, octave on wsl.

One note for Cygwin octave
libGL error: Windows-DRI extension not available

appears after
plot(1:10)

However, octave hangs --nowgl for VcXsrv for X11 forwarding.

I think that this is an issue of X-sever for windows.

For me,
--nowgl for VcXsrv, crash octave at plot(1:10)
--nowgl for Cygwin-X , no change at plot(1:10)

In general plotting problem on Cygwin are due to GL driver issue
and usually both fltk and qt are impacted.
Try running the X server with "-nowgl" option.

I have built 5.0.90 on Ubuntu 18.04 on WSL windows 10.
The result is the same with that of 4.4.1.

I add Marco Atzeri to the CC.list because he is a maintainer of octave fot Cygwin.

How about qt graphics_toolkit on octave on cygwin, on your environments.

To Rik.
I have not built 5.0.90 on WSL (Windows Subsystem for Linux) and Cygwin. I have built it on remote Ubuntu 16.04 (X11 forwarding).

For octave 5.0.90 on remote Ubuntu 16.04 connected with windows though ssh with X11 forwarding and with Xsrver on windows,
the situation is the same as that in 4.4.1.

@Tatsuro: Is this still a problem with the release candidate 5.0.90?

I currently do not install GUI on remote machine.
I will prepare another Ubuntu PC for the test.
It takes a little bit time to test it.

To clarify:
I cannot reproduce this problem with current octave (either
dev or stable). But I used to have some problems with
octave and some other graphical programs running through ssh forwarding. At the moment I still have an issue with eog and evince e.g... (Okular and gwenview  work fine).

Can you start an xterm on remote machine?

Sorry my description might be poor.

I am using linux version (including Cygwin) on Windows.

X server application is working on windows 10.
1. VcXsrv
2. Cygwin-X

Octave 4.4.1 is working on 

1. Cygwin x64 on the same windows 10 PC
2. Ubuntu 18.04 on Windows Subsystem for Linux (WSL) on the same windows 10PC
3. remote Ubuntu 16.04.5 connected with "ssh -XC" (X11 Forwarding)

I tested X-server on Windows 10 (VcXsrv and Cygwin-X sever).
I have to test X-sever on linux but I need time to prepare another machine to install linux with X-sever.

I suspect this is an X11 (Wayland?) issue.
Does your Ubuntu run Wayland or Xorg?
On my machines if I run "eog some_picture.png" on remote machine it pops up window on the remote machine rather than on local.

The result was the same.

I have tried to use octave X-client and X-Sever system.

Octave version is 4.4.1

X-Sever
 VcXsrv on windows 10.
X-client
 Ubuntu 18.04 on WSL
 Cygwin x64
 Ubuntu 16.04 connected with "ssh -XC" (X11 Forwarding)

On the system,

plot(1:10)

with qt graphics_toolkit gives blank page or other images of other X-client software or thread.
