some game does not handle cross fading

[jeff1234]

hello all ,

i just tested my favourite AVG "aozora" (青空に約束)
with 0.76 , the game just show black screen, or wrong color screen with buffering off

with current nightly build, the game does show some screen correctly, however it crash on the cross fading effect, when front picture alpha decrease and another picture fade in, it die

---

crash means, it freeze and does not accept input.
when two screens merge together with half alpha, it happens.
