It sounds like they don't understand the bug. We're not swapping buffers when rendering to the front buffer.
Maybe if would provide me with more info on the nature of this bug, I could then attach it to my bug report on Apple Bugreporter.
I'm not a programmer myself, but I'm doing my best to make sure that Apple knows about the issue.
