MacOS: Crash related to startup window
When toggling the fullscreen checkbox in the MacOS startup window after launching either Mapster32.app or EDuke32.app, I receive the following error:
Here's a backtrace of the issue:
This occurred using a MacOS Catalina 10.15.5 VM on Virtualbox. I also have a report of this exact error occurring on a physical Mac, where the crash even happens without needing to toggle the button. Compiling using STARTUP_WINDOW=0
resolves the problem in this case.
