I am not sure, if you are searching for a workaround or collecting data for filing a bug?Bit of both, I guess. I was hoping there was a workaround, and trying to find out if it was just me. I'll file a bug. I know the Core Image Accumulator can be used, but the Feedback patch should also work without bringing my machine to it's knees within a few seconds. a|x You can certainly do the same feedback thing with an image accumulator patch. best, Achim Breidenbach Boinx Software On 09.02.2011, at 11:25, Alex Drinkwater wrote: > I've noticed what seems to be a massive memory leak when using the Feedback > patch with images.
