Refresh needed after Remote Desktop Connection

Refresh needed after Remote Desktop Connection

[Trollope, David]

Hi,

I've been encountering a new behaviour recently which I'm hoping someone 
can shed some light on or suggest some tweak that will help.

I regularly remote desktop to a machine running cygwin with an X server 
running - it is a Window 7 Enterprise box.

The act of connecting through RDP resizes the screen. Normally the 
machine runs with two screens.

After connecting with RDP (and while connected) the X windows do not 
refresh. I typically have open multiple xterm's but nothing refreshes. 
Until I move a window, it will not refresh. as soon as I move a window, 
it becomes usable again. I.E. xterm's do not display what is typed until 
the window is moved.

This seems to affect all X windows. Any ideas?

Cheers
Dave

When you say this is 'new behavior', when did it start? When you upgraded the 
cygwin X server? or something else was changed?

So if I'm understanding you correctly, the contents of the windows are drawn 
correctly after the display resizes, but then do not update?

What about the root window, does that have the correct contents?

If you run a simple X client such as 'ico' or 'xeyes' does that continue to 
draw correctly after the resize, or not?

This is quite possibly a bug of some kind in the resize handling in the X 
server, although I don't have any particular insight at the moment as to what 
that bug might be :-)
