Video issues/tearing/flickering

@Franko, I’m not sure that I can follow. I might need some more details. I recommend you to install Anthias on a Raspberry Pi 4 running Raspberry Pi OS Lite:

  • Download the Raspberry Pi Imager from this link: https://www.raspberrypi.com/software/.
  • Open the Raspberry Pi Imager app once installed.
  • For the Raspberry Pi Device, you can choose No Filtering.
  • For the Operating System, select Raspberry Pi OS (other), then choose Raspberry Pi OS Lite (64-bit).
  • Choose a storage device where the OS can be flashed.
  • Click Next.
  • Feel free to customize the settings (e.g., hostname, username, password, etc.) if you need to.
