Hi, I have 2 viewers (based off of osgsimplepager) that are looking at the same scene graph which is an OverlayNode that contains a terrain model among things. I'm drawing various geometry in the OverlayNode like grid lines, etc.
The issue that I'm having is that my application works fine on my desktop machine (NVidia GeForce FX 5200), but only if I share graphics contexts using RenderSurface::shareAllGLContexts(true). This machine is falling back to using the PBuffer implementation of CameraNode. If I don't share contexts, only one window gets the updated overlay. I have a laptop (NVidia GeForce Go 7900 GS) that uses FBO in the OverlayNode. Things work on this machine only if I don't share graphics contexts. Well, they work for awhile until one of the windows freezes up. I guess my question is: What is the correct/safest way to share the contents of an OverlayNode between multiple windows?
