Hi Eron,
I'm not a windows developer so can only comment in general. My
thought is that it could well be an issue with the windowing systems
addition of the shadow not playing well with double of the OpenGL
window with the drivers you are using. I kinda doubt there there will
be an option we
Hi,
we are having the same issues here and I think the problem is related to
multithreading.
One solution may be to sync your drawing thread to the drawing of
windows or to sync the swap operation in double buffered mode.
I don't know if that helps, it's just a guess.

No it's not multi threading. My single threaded non OSG apps do the same,
and that's with my OpenGl rendering code called in response to WM_PAINT.
It's something to do with the back buffer swap overwriting the screen
without being properly synchronised with GDI but I've never had time to

Robert is quite correct; it's nothing to do with OSG.

My raw OpenGl programs have the same problem
and so do quite a few other none OSG programs.
I've never been bothered enough to investigate myself though.
A quick dirty solution is just to disable screen updates when
Curious. Could you provide a really stripped down program which
doesn't have dodgy menus? mfc / atl or raw win32, as I don't have
any other GUI toolkits setup.
I can make one out of my programs but you've already looked
at one wrong program so another wrong one isn't going to help...

The issue seems like it may be with vsync.
When I setup my video card to enable vertical sync by default, the
problem is a lot less pronounced (arguably good enough not to worry
about). I'm guessing the programs that seemed to work were explicitly
enabling vertical sync.
I believe I've
When menu shadows in Windows XP are enabled, I get a flickering artifact
where some menu shadows overlaps with the area being rendered. This
happens with the build in examples, such as osglogo.exe. I'm allowing
the osgViewer module to create the window, using the OSG_WINDOW
environment
