Yes, works perfectly while only one screen is connected. That means, 
this definition of "fullscreen" is "the whole framebuffer", and not "the 
content of one display"? This would in some way explain why tearing can 
not be reliably prevented while more than one screen is active.

Thanks for the explanations!
