Possible fix for Kyra CD intro glitch
|Reported by:||eriktorbjorn||Owned by:||lordhoto|
I had a sudden flash of inspiration about the Kyra CD
intro glitch, where the image goes almost black at the
beginning of the "tree2" movie.
Since each new frame is XOR:ed with whatever was there
before, the screen going black would mean that the
decoded frame data looks just like what's already in
the destination buffer. So to keep that from happening,
all we have to do is to make sure the buffer is cleared
I don't know if this patch represents the correct way
of doing that, though. But it does fix the
aforementioned glitch for me.
