I started to follow up Howard's report that he could still see graphical corruption with these patches, and I was surprised to notice that it had reappeared locally once again :/ After working out that this was because the relevant instructions weren't being generated for all Mac machines, I was able to figure it out after a few hours of digging. Patch to follow shortly. ATB, Mark.
