Hi Glenn, I have only personally testing compile contexts under Linux and haven't seen any error like your describe. I've just done check against a paged database using --cc with osgviewer and things are working as they should.
Problems you are seeing code by a threading bug in the implementation that the linux build isn't sensitive too, or it could be a bug in the pixel buffer implementation, or it could simply be a bug in the OpenGL driver. Which? I can't say, I'm afraid this is something windows developers will have to debug. Robert.
