Indeed, QT seems to have some issues using CoreVideo on
configurations
with multiple cards, even if all are supported. First make sure you
have the latest OS & QT updates.
I have the latest QT 7.1.3 and all updates installed. Quicktime
player still goes white when I drag a quartz composer movie
(windowed) onto secondary displays on additional graphics cards.
Is this supposed to work on all displays? Should I log a bug?
You should yes, it's definitely a QT bug
Is it a case of "fixed in Leopard"?
I actually don't know
