Thanks Chris, unfortunately I can't run it on 64bit since I'm also using 32bit only QTKit methods. With instruments, I see some 160 bytes leaks when initing QCRenderers, but it seems to be problem a problem with 3rd party CIIFilter, the stack trace looks like this all the time:
0 libsystem_c.dylib calloc 1 CoreImage sl_value_new_scalar 2 CoreImage sl_value_base_subst 3 CoreImage sl_program_reg_unalloc 4 CoreImage compile_kernels(gsl_parser_struct*, gsl_decl_struct*, void*) 5 CoreImage gsl_parser_foreach_kernel 6 CoreImage +[CIKernel kernelsWithString:messageLog:] 7 CoreImage +[CIKernel kernelsWithString:] 8 BC Image Unit -[RGBGammaContrastFilter init] 9 CoreImage -[CIFilter initWithCompatibilityVersion:] 10 CoreImage +[CIFilter(CIFilterRegistry) filterWithName:compatibilityVersion:] 11 CoreImage +[CIFilter(CIFilterRegistry) filterWithName:] 12 QuartzComposer +[QCImageFilter isCIFilterCompatible:] 13 QuartzComposer _RegisterPatches 14 QuartzComposer +[QCPatch(Registry) patchManager] 15 QuartzComposer QCPatchFromCompositionWithOptions 16 QuartzComposer -[QCComposition _makePatch] 17 QuartzComposer -[QCComposition patch] 18 QuartzComposer -[QCRenderer initWithCGLContext:pixelFormat:colorSpace:composition:] Anyway, the user rendering in full-hd resolution, so as you mentioned, this could be a problem. Is there any method to check the Core Image filters will have enough available method to allocate?
