Hi,
I use the method from the QCTV example to play a quartz composition
with the difference that i use a qcview and then the opengl context of
it to render the qc instead of creating the opengl context myself.
This works like a charm with my iSight on a power mac G5, but when i
try it on an intel imac, the second time i start the program, the
image starts to flicker extremely. If i enlarge the screen the flicker
dissappears, but when i start the recording process, the flicker comes
back. What can be a possible cause for this? How can i get rid of it?
