Hi,
In the latest Rhino 8 WIP (8.0.23024.12306, 2023-01-24) for macOS, layout details seem to move away from where I zoom in to by scrolling with the middle mouse button. When I zoom back out, all falls back into place.
The setup here is a single scaled layout detail (1:10 units) and some red and black text that is local to the Layouts view only. Rhino has been running for around two full days now.
My current system info can be found in this thread.
Update:
I just rebooted and it’s still the same.
