Hi J-S,

Hmm, what is strange is that the modified (extremely hacky) version
attached does not crash and seems to work. It just uses a shared
context, so maybe there is something in the context vs vertex array
that is not working properly.
Yes, well one of my hunches was that something in the context
creation/reuse was buggy, since the problem appears because we're
creating, then deleting, then creating contexts. I've traced into the
code of the effect, and the same context ID seems to be reused the
second time the secondary view is created (3rd 'a') as the first time
(1st 'a'). That means that when getting the osg::Drawable::Extensions
object, the same one that was created for the old context is reused for
the new context.
Did the shared context version I previously attached work on Windows?
Just curious. When I tried it on Linux I could add/remove many times.
