Seeing the same issue, in addition to seeing it on the first 3 navigators (⌘1-3). It didn't work like this in previous Xcode versions, as I often leave the dev doc window open in the background. Filed feedback FB8949830.

Submitted bug report FB8710561 for this issue
Yes, the shutting down after multi-buffering is where I'm seeing the problem. This sample code is what I've been following for some of my implementation (https://developer.apple.com/library/archive/samplecode/AdoptingMetalII/Introduction/Intro.html), even though my implementation is more complex as depending on what I'm rendering, only some of the buffers are going to be in use, so their associated semaphores end up getting deallocated. I'm definitely open to a better solution to this semaphore problem if there's one that doesn't involve a workaround. Thanks!
