I have been playing the game for some time and a problem ocurre, sometimes when I'm in battle, the imagen goes off, and than it returns after i finish the battle, what is the problem?

Is that with the beta? What settings?

I remeber that bug.
the battle scene comes back if you change vetisphere, too.
dunno if it has been fixed, though.
I think software mode fixes the problem.

I'm in default seatings and some speedhacks, i will try to prove de vetisphere change

I would try without the speedhacks.

doesn't matter eitherway, and software mode does NOT fix it.
