Nice, I'm assuming you are doing this in the desktop environment? I'd be curious to see if it can be achieved outside that as my project is focused around a single full screen app, such that the desktop environment will be wasteful to use. My tests have been done on the Pi OS lite without desktop.Increased SPI frequency to 64MHz - ran camera preview in GUI -> no tearing at all, but see some lag in the preview. My V2 camera gives me 30frames when running 'libcamera-hello -t 0'. Used an ACC to rotate the screen while testing -> no tearing visible.
Will check something else tomorrow (in the init command binary) and see if I have time to test your demo.
Can you share a video recording of what you are seeing? I'm attaching here a video of the demo SDL2 app demonstrating the tearing artifacts:
