This means you'll need to run SingleThreaded or drop the shared contexts. The OSG doesn't mutex lock GL objects for a single context as the costs would be prohibitive, and it's only required for shared contexts usage so it's not a penalty that is worth paying. > > I do set this member for all my contexts.

I would suggest fixing this problem, or just go with shared contexts and SingleThreaded. Robert.
