It's difficult to say what could be going on without seeing some code.
At this point, the best you can do is create a sample case and open a
bug report on bugreport.apple.com

My rendering into the CV buffer just shows up as black (which is
also my clear colour). My software can be used into two modes:
integrated with QC and without and "without" works fine; thus I
don't think there's a problem with my actual rendering. Plus this
all still works on Tiger.
This behaviour is re-confirmed.
- any error messages in the console log?
None.
Zip.
- if you compile your app on Tiger and run it on Leopard, does it
work?
I'll check again but from memory I simply ran my Tiger-built
application on Leopard and witnessed the anomaly. I then
subsequently tried things out having built using Xcode 3.0 and no
difference; still the anomoly; but I'll check again.
App compiled on Tiger works on Tiger but not Leopard.
the Performer sample code in QC examples does work on Leopard and
uses CVOpenGLBuffers too - have a look in case you're doing
anything different?
Will do. I'll get back to you within 24 hours. Thanks for your
attention.
Performer is different in respect of rendering via a display link.
Mine doesn't render via a display link.
BTW: here's our original dialogue on this where you outlined the
approached and I fleshed it out with some code:
