Check gl modelview and projection matrices just before terrain rendering (in draw callback f.e.). Also you can use gDebugger or similar tool to get snapshot of opengl state just before terrain rendering with SpeedTree stuff in scene and without it, difference will give you a clue about what's

HI Mikael, Thanks for the details. Your comment about the delete not being mutexed made me think about why the ref count could get to zero and then have the thread progress to delete, and one shouldn't progress to delete as long as the ref count is non zero. This led me to wonder just how with
