Pro-C3 fullscreen secondary screen not working
That's interesting. We've seen quite a few graphical issues after the update to Logic 12. We'll investigate if this is part of the same problem. Did you happen to start seeing the issue after updating to Logic 12?

basically title.
if i put into fullscreen on secondary screen, GUI freezes and i have to close/reopen GUI.
it's also not working on ProQ4, which is odd because i'm fairly certain i had that working at one point
Sequoia 15.7.3, Logic 12.0.1
