Ah, I guess this is why I'm seeing "GPUTop" at the title bar :P

I'm not sure what's going on here, but now when I close the window by
clicking on the "x" at the top right I see this message:

aubinator_viewer: ../../src/libepoxy/src/dispatch_common.c:863: epoxy_get_proc_address: Assertion `0 && "Couldn't find current GLX or EGL context.\n"' failed.

That's the only issue I've seen so far, and since it's only when closing
the window, I guess we can fix that later.
