We encountered a nasty problem that I wanted to make people aware of so nobody else gets bitten in the same way.
- The bug appears in the Unsharp Mask filter. - It only seems to happen if the filter's image input is another Core Image filter. - It only happens on the Intel 3000 graphics card (new Macbook Air (and others?).) - It only happens when the unsharp mask filter's Radius input is set to 0. It's pretty obscure, but it manifests itself in the Sharpen composition as well because that uses the Unsharp Mask filter. Virtual memory ticks up very rapidly (about a gigabyte every 10 seconds, so watch out not to run for too long because once hard disk space is exhausted the system can hard freeze and you'll have to hard-restart. Anyhow, here's a very simple composition showing the problem in case anyone's interested. I suppose I'll file a radar on this as well. Again, it only seems to leak on the new Macbook Air. Run this composition in Quartz Composer and look the memory tab in Activity Monitor and you'll see the Virtual Memory skyrocket. http://ecamm.com/Composition.qtz.zip -Ken _______________________________________________ Do not post admin requests to the list.
