JUCE in Rosetta - CurrentVBLDelta errors (with OpenGLContext)

On the latest Xcode I’m getting zillions of these running an app under Rosetta. There are so many of them it’s causing problems debugging (which I’m having to do under Rosetta because of the bizarre vtable issue … it’s really not my week!)
