I'm writing a swift app that uses metal to render textures to the main view. I currently use a NSViewRepresentable to place a MTKView into the window and a MTKViewDelegate to perform the metal operations. It's running well and I see my metal view being updated. However, when I close the window (either through the user clicking the close button or by programatically using the appropriate @Environment(\.dismissWindow) private var dismissWindow) and then reopen the window, I no longer receive calls to MTKViewDelegate draw(in mtkView: MTView). If I manually call the MTKView::draw() function my view updates it's content as expected, so it seems to be still be correctly setup / alive. As best as I can tell the CVDisplayLink created by MTKView is no longer active (or at least that's my understanding of how the MTKView::draw() function is called). I've setup the MTKView like this let mtkView = MTKView() mtkView.delegate = context.coordinator // My custom delegate mtkView.device = context.coordinator.device // The default metal device mtkView.preferredFramesPerSecond = 60 mtkView.enableSetNeedsDisplay = false mtkView.isPaused = false which I was hoping would call the draw function at 60fps while the view is visible. I've also verified the values don't change while running. Does anyone have any ideas on how I could restart the CVDisplayLink or anyother methods to avoid this problem?? Cheers Jack

I have a very basic usdz file from this repo I call loadTextures() after loading the usdz via MDLAsset. Inspecting the MDLTexture object I can tell it is assigning a colorspace of linear rgb instead of srgb although the image file in the usdz is srgb. This causes the textures to ultimately render as over saturated. In the code I later convert the MDLTexture to MTLTexture via MTKTextureLoader but if I set the srgb option it seems to ignore it. This significantly impacts the usefulness of Model I/O if it can't load a simple usdz texture correctly. Am I missing something? Thanks!

Project: I have some data wich could be transformed by shader, result may be kept in rgb channels of image. Great. But now to mix dozens of those results? Not one by one, image after image, but all at once. Something like „complicated average” color of particular pixel from all delivered images. Is it possible?
