AMD OpenGL drivers refuse to build shaders with no specified version if Core Profile is enabled.

It seems that the GLSL version numbers are not specified in the shader source provided in the OpenGL module. I enabled the Core Profile, and tried to construct a QPainter for 2D overpainting, however the application crashes after trying to compile the internal Qt shaders.

Errors:
