You’re right, explicitly requesting the compatibility profile causes the
pyramid to appear with GL 3.3 / 3.2 contexts.
By default, it seems my machine uses the core profile whenever I request a
recent enough GL version.
However, if I request an older GL version (< 3.0) or don’t explicitly
request one at all, I get a 3.3 context with the compatibility profile.
I should mention that in all cases, glfwGetWindowParam() returns 0 when I
ask for the currently used profile.
