I'll have to check the version number that the context returns. I'm just confused why in this situation, the GL object returned is a GL2 object even though I requested the GL3 implementation. In the example fix I linked to, they did something similar in java swing, so I'm not sure if I have to do some radically different in QtJambi. In the swing case, there's a GLCanvas object with specified constructors that handle these contexts and profiles. With QtJambi, I don't think these kinds of hooks exist in the API. > I'm curious whether you can confirm that behavior. Which behavior?
