Исправление Behem0th, (текущая версия) :
https://cgit.freedesktop.org/mesa/mesa/tree/docs/relnotes/11.2.1.html
Mesa 11.2.1 implements the OpenGL 4.1 API, but the version reported by
glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used.
Some drivers don't support all the features required in OpenGL 4.1. OpenGL
4.1 is <strong>only</strong> available if requested at context creation
because compatibility contexts are not supported.
иначе уже была 13-я версия
Я про то и говорю, должна быть и не апают.
