Jiggle is purple because there is either an interaction or mouse patch hidden in it, as it is a virtual patch (can't remember which, and I'm in 10.5.8 right now so it's a pain to check).... the mouse/interaction makes it externally driven.
Also, on my system, Mesh Bulge has been working- there is no problem with it, it's Mesh Bend that's been broken, along with Mesh Noise (since 10.6.2 or some 10.6.1.whatever). Some DAE's don't render at the same scaling or rotations as they did on original release either. It's good to know that for some, this version is working better, but this *definitely* isn't as stable as the original release of QC4, on my system (nVidia 9400/9600 Macbook Pro). I don't want to seem like I'm beating up on it, I just think the praise is unrealistic, especially for anyone who has to consider something running on machines of differing configurations. It's more realistic and sane to avoid OpenCL in QC at this point, and work around other bugs that have been introduced since QC3 as best possible. For someone to design an app around, say, QC rendering DAE's, and have a simple OS update change all scaling and rotations is pretty unacceptable, and that's square one. It's hard for anyone to take OpenCL and the Mesh Kit seriously. For things like mesh filters to have regressed is also unfortunate. That said, QC4 is definitely usable, and there are some great things about it.
