Just trying to Flipbook in 12.5, Mplay opens and outputs the specified frame range but the frames are all black.

However Mplay seems to work fine when rendering in Mantra etc. Any one else experienced this or know how to resolve it?

I've also updated my GFX Card Drivers with no success.

That happens to me to ! about 60% of the time.

I can't recreate either behavior at will.

Anyone has a take on this ?
