Hello, This exact question was already asked in this forum (8 years ago) but I can't find a definitive answer: Does Metal allow using the same color texture as both an input and output (color attachment) of a fragment shader? Is the behavior defined somewhere? I believe this results in undefined behavior under both DirectX and OpenGL, so I'd assume the same for Metal, but then why doesn't Metal warn me about this as it does on some many other "misconfigurations"? It also seems to work correctly in my case, as I found out by accident. Would love to get a clarification! Thanks ahead!

Hi, I tried updating to Xcode 13.3.1 through the App Store but it's as buggy as usual and got stuck. I know @eskimo recommends downloading Xcode releases manually, but 13.3.1 doesn't appear to be available there (only the command line tools package is there, see screenshot). wtf?
