Composition mode crash after moving Scrivener to second monitor

Scrivener Beta Testing (Mac)
1

To reproduce:

Load Scrivener on primary monitor
Switch to Composition mode.
Switch back to non-composition mode.
Move Scrivener to second monitor.
Switch to Composition mode.
Crash.

Exception Name: NSGenericException
Exception Reason: *** Collection <__NSArrayM: 0x600000567c30> was mutated while being enumerated.

I tried this with more than one project.

Hmm, I’ve tried this but I’m afraid I cannot reproduce it. I plugged my MacBook into an external monitor, fired up composition mode on my MacBook screen, exited, then moved the window to the external monitor and fired up composition mode there - no crash. Could you please post the full backtrace?

Thanks and all the best,
Keith
