looking into the source and inspecting the stack-trace I would say this crash has nothing to do with osgText. It seems that the implementation of GraphicsWindowCarbon:: setWindowDecorationImplementation is the culprit, it removes the opengl context from the window surface and reattach it again. This is certainly a no-go when another thread is trying to render stuff into that context. I marked this behavior as a hack in the source, when I coded the implementation but I did not find another reliable way to regain access to the whole space oocupied by the window after removing the titlebar. I'll try to look into this next week, hopefully there's a slot of spare time to do it. cheers, Stephan > > Cheers, > Hartmut > > > > > Process: osgviewer [1487] > Path: /usr/local/bin/osgviewer > Identifier: osgviewer > Version: ???
