Enabling VSync should take care of tearing; I think the VESA spec has a way to
enable that feature internally without you writing code for it.
Also, proper double buffering will go a long way towards eliminating tear and
flicker.

Hello Mr. Bertho,
Thanks for the tips. However, I suspect that knowing when exactly
vertical retraces occur is still relevant to modern monitors (and OSes),
where one needs to prevent "screen tearing" and other nasty artefacts.
So I would think it is still useful to know how to do it right.
