Hey sorry, I didn’t have time to try the OS downgrade. It’s still something I want to try. Meantime, I’m wondering if the dropped frames error is bogus. I turned it off the warning and I can’t see any dropping frames. If I turn the warning on, the error pops up within a second, though.
Are you seeing the dropped frames or just the warning message?
