[vtkusers] Problem in SampleMFC test?

The problem is in the Windows 98. I have an OpenGL based program that had a
similar problem (black right and bottom edges) with Windows 98. The problem
might be solved by updating your graphics card driver, or turn off (or reduce)
the hardware acceleration.

Hi David and Nigel,

If it comes from my hardware, I will almost be happy.
One point is that there is a single actor in the sample, which does not require
a lot of memory. The strange thing is that I obtain the same odd behaviour when
I run it in 640*480*8bit. How memory/hardware could explain that? Sound a bit
strange, no?

Hi Jean-Do
   I experienced something similar some years ago. I never really resolved it,
and the problem went away when I got a new computer. My guess is that the
problem is at a lower level, ie graphics hardware, (or perhaps OpenGL).

A quick look in the archives turned up this:

So someone else has had this problem too. I could not see any solution given,
you could look harder in the archives for an answer there.

-Try turning off hardware accelerations in Windows (right click desktop, select
Properties | Settings tab | Advanced button | Troubleshooting tab (and other
tabs)......  probably different under W98...) -Can you try your application on a
machine with more (graphics) memory? -Don't run fullscreen...

    bon chance

I've compiled the vtk4.0 MFC sample test (located in
Examples\GUI\Win32\SampleMFC) with VC++6.0 (sp5) under Win98. When running the
exe in fullscreen mode 1024*768*32 (the main frame and the child frames), there
is a  bug which can be easily seen by set background to white in
vtkMFCRenderView constructor :

Then, you just run the exe and you open several child windows. You (at least I
do) should get a black area at the right and bottom part of the window that
increases in size as more and more child windows are opened.

It sounds like a problem between Win32 and vtk?
Does anybody obtain the same behaviour and/or has a clue where it could come
