Not really...
As I remember, it was very casual when the effect came or not. I bet, it was a floating point number rounding problem...
The most painfull thing was the long texture binding time.

I'm sure, it is more cleaner solution to have one bigger texture, even if some software scaling magic is needed.
The implementation is also closer for newer and for older video HW.
