It seems I wrote that too fast. After downgrading I switched it back to OpenGL
and it said something like "OpenGL is disabled, because it crashed. If you
think you have working version now, save all your work and click this to retry
it. Warning, might crash immediately." So it was selected, but apparently
wasn't actually used.

Yes, it does. The frame-rate was as expected and it decreased when I enlarged
the window to full screen exactly as it does when everything works.
