This is a very confusing topic. In my code, I am using QOpenGLFunctions_1_2, and it is working. But each plugin that uses OpenGL must do this, and it's unclear what version should be used. I simply used the minimum version that supported the functionality I needed. It's also unclear what happens of two different versions are used in the same application.
