I can confirm this, latest AMD drivers are seriously broken. I can't create anything but a 3.2 core context (even though it says it's a Compatibility context), all deprecated functions are missing.
If I use no ContextAttribs or ContextAttribs with any version < 3.2, I get a 3.2 core context.
If I use ContextAttribs with 3.2 and Compatibility profile, I get a 3.2 core context.
If I use ContextAttribs with 3.2 and Core profile or no profile at all, I get an OpenGL error on context initialization.
A joke indeed.
