Be careful when using QC under GC, as since it relies on many other
graphics technologies and does high-performance media processing and
the later is not really GC friendly, you will likely end up with poor
performances.

For reference,
I managed to get the app working without GC until the first few
renderings (crash would occur just after), then could break on error
in OpenGL profiler.
The error is due to this:
glTexParameteri(GL_TEXTURE_RECTANGLE_EXT, GL_TEXTURE_WRAP_S,
GL_REPEAT)
which apparently is a bad combination (yet it does work, texture
repeating), detected by QC. I changed it to GL_TEXTURE_2D.
Thanks,

Hi,
Well, this is not an option for me, OpenGL Profiler is broken for
garbage collected apps, mine won't work without GC. Do you have
another option to track that error ?
Thank you

Run your app under OpenGL Profiler with "break on error" and you
will see
which call fails
Make sure you are not doing invalid GL stuff before calling QC

Hi,
I've set up an OpenGL view in which I render using a QCRenderer.
The first
time I render it, I get this error in the log and nothing renders:
*** OpenGL error 0x0500 (invalid enumerant) in function "-
[QCOpenGLContext
willPushRenderState:]"
There are no more errors from the second rendering and after.
This is a pretty simple composition taking CIImage and
NSBitmapImageRep as
inputs.
Any advice on this ?
Thanks,
