    In short, the upgrade to v2.4.1 was a chore. Turning on either OpenGL driver from the /boot/config.txtfile prevented the Pi from booting. Eventually, the SD card became corrupted and I had to re-flash the Raspbian image. After that, the install went pretty smoothly. It just took time.

    However, now I’m getting this weird flashing effect on my mirror. It seems to be at the OS level, as restarting the MagicMirror process through pm2 didn’t solve the issue. Rebooting the mirror did make the effect go away, but I’m not sure for how long. I’ll provide more updates as I collect more information.

    Here’s the effect:

    Any help would be appreciated.

      Problem resolved. I did two things:

      1. Moved to the real OpenGL driver, not the fake one.
      2. Changed the resolution of the Pi to “Monitor Default” instead of hard-coding to my monitor resolution.

      I don’t know which of these two did it, but I haven’t experienced the graphical problem since.

        After a day, the flashing effect seems to occur about an hour after mirror boot. So far, it has occurred twice. Rebooting the mirror seems to be the only way to fix it.

        Stopping the MagicMirror process will drop me back to the desktop, but it will still have the graphical corruption.

            I had the same issue just recently and can confirm that switching to full KMS solves the issue.
            Don’t know the reason for this however.
