I would guess desktop panning is more like 15fps, and each of those frames get refreshed 4 times at various stages, leading to the tearing we see. If we drop the refresh rate to 30hz, we'll halve the number of visible artifacts.
hmm then isnt it possible to use some sort of a potential optimiser which would just scale the fps up to 30? I mean if you observe what is the minimum and max it goes to and then you can apply some gain just to scale it up to something between 25 - 30 (i dont even know if this is possible at the software end .. youre the pro :P ). but i guess thats where alising problem comes in right?

I believe (like you said earlier too) that the fps are just kept so low just to save power.

I know C too but im not so good at it. im just trying my best to help you out but putting in some ideas.
