The 828 seems to be fine, as is everything with Logic except the display. I've tried checking all my prefs, trashing my prefs... it's like Logic is having trouble redrawing the screen, but I've changed nothing about my monitor or display settings. Even the song position line is not scrolling smoothly, but in big jerks (ditto the song position numbers in the transport, the numbers are jumping rather than smoothly incrementing). The audio is fine, though... Anyone have any ideas on this? It's driving me batty...
