(KVO) Crash on exit #26

Open MaddTheSane opened 3 years ago

MaddTheSane commented 3 years ago

There's a crash on exit due to Key-value observing not being happy:

2021-04-05 12:35:41.568218-0600 Boxer[13480:13258843] [General] Cannot remove an observer <NSKeyValueObservance 0x600001ac4870> for the key path "currentFrame.scaledResolution" from <BXMetalRenderingView 0x12a990600>, most likely because the value for the key "currentFrame" has changed without an appropriate KVO notification being sent. Check the KVO-compliance of the BXMetalRenderingView class.

Typing EXIT in the DOS prompt doesn't cause the crash.
