I've been attempting to use the new CAMetalDisplayLink to simplify the code needed to sync my rendering with the display across Apple platforms. One thing I noticed since moving to using CAMetalDisplayLink is that the Metal Performance HUD which I had previously been using to analyze the total memory used by my app (among other things) is suddenly no longer appearing when using CAMetalDisplayLink.

This issue can be reproduced with the Frame Pacing sample from WWDC23

Anyone from Apple know if this is expected behavior or have an idea on how to get this to work properly?

I've filed FB13495684 for official review.

@DTS Engineer I can confirm this is now working as intended with macOS 15 beta 2 and Xcode 16
