I am running windows xp nvidia 7600gs, with the latest drivers. Forced
Vsync option enabled. I get 100% vsync when I move windows around
rapidly and take screenshot.

I get 0% vsync doing same thing on latest kubuntu, with latest
proprietary nvidia drivers, and open source "nv" driver, with all
vsync options enabled. Strangely, I do have fps cap at 60 fps on glx
gears. Yet applications visibly tears apart if I move them around too
fast, movies also tear apart mid frame, even though my pc is more than
fast enough to handle full hd video playback without tearing on
windows xp.

What really is the issue perhaps might be, there is no concrete way of
testing if vsync is working besides high speed window movement and
printscreen. Most other bugs are easily verified, yet vsync is hard to
confirm on a stationary screen. Anyone care to develop a program that
reads the framebuffer and determines if vsync is working?
