Missing Opengl extensions with Qt 5.5.1

I just set up a new arch linux environment and now i am experiencing strange behavior. Openflipper reports my graphics card does not support the GL_ARB_vertex_buffer_object extension which is wrong since i have an opengl 3.3 context.

i investigated this since someone else told me about the same behavior a few months ago. i attached the output of openflpper and made it print all extensions found in QOpenglcontext.extensions()

as it turns out my glxinfo shows the mentioned extension, while qt doesn't. when i hit the ignore button openflipper starts, but the window is never repainted.glxinfo_output openflipper_output
