I have multiple CAMetalLayers that I render content to and noticed that the graphics overview HUD does not function properly when I have more than one CAMetalLayer. The values reported will be very strange. For example, FPS may report 999 or some large negative value. It the HUD simply not designed to work with multiple CAMetalLayers or MTKViews? When I disable all but one of my CAMetalLayers, the HUD works as expected.

Hi. We are investigating issues using Metal HUD when multiple CAMetalLayer are present. For better investigation we'd appreciate if you're able to submit a Feedback Assistant Report with the issue and with a sample (if possible), and provide the feedback assistant ID here. Thank you.
