      Hello fellow mirror builders. A newbie asking for help :smiling_face_with_open_mouth_cold_sweat:

      I’ve encountered an issue in which the screen will start to “flash/glitch” after 10 or so minutes of otherwise perfectly fine operation. Link below:

      Magic Mirror Glitch

      Now, here are some things that I have tried to troubleshoot:

      • Read somewhere that it could be a hardware issue with the pi itself. I switched to another pi I had from an old project and tested it on that. Exact same issue, and I know that pi should be fine.

      • Tried connecting to a different monitor. Same thing was replicated on that monitor too.

      • I stopped the mirror (pm2 stop mm) and left the pi running to see if it would happen anyway. Without the Magic Mirror running, it did not glitch.

      output of pm2 log MagicMirror:

      pi@black-mirror:~ $ pm2 log MagicMirror

          As you are operating your mm in portrait mode, maybe it is an performance issue.

          Here is a link you can try https://forum.magicmirror.builders/topic/9707/save-performance-when-rotating-screen-e-g-on-raspberry-pi

          Maybe this helps.

            @Mykle1 you are my favorite! That link totally did the trick.

            At the end of the day, it turned out to be that HDMI issue. All I had to do was use the Open GL driver instead of the fake one and use Xrandr to rotate the screen after the fact.

            So far it has run smoothly without any incident. I’m gonna mark this as solved.
