Dear Robert and other QCCompositionLayer programmers...
You have good timing. Having not touched this code since last fall,
yesterday I started creating QCCompositionLayer code. The composition
works fine if the background is solid, but when it is transparent, I
see artifacts and flashing. This sounds identical to Roberts issues.
Does anyone know what is going on? My QCCompositionLayer is on the
screen with several other transparent CALayers, and they all need to
behave nicely together.
Is this a known bug?
Second question, I am having problems having my own Quartz Composer
composition animate in the above example. If I used one of the QC from
the Composition Repository (ex. defocus) within my own program using
QCCompositionLayer, then they animated perfectly. When I use my own
composition, it does not. My compositions animated inside of Quartz
Composer without any modifications. Is there a setting that I need to
switch on for animation to work within a layer? I am not doing
anything fancy, just some Particle System animation (yes, I am using
QC to animate an About box).
Thank you!
