Hi
I have some problems too. In my case, it happens on RPI zero 2 on GPi case, after boot video, the loading image starts doing some weird stuff. I've recorded a video to show you, because it would be hard to explain what's going on... https://www.youtube.com/watch?v=d2uSG4D7QQw
Funny thing's you can control the menu, but you can't see what's selected. The background music works perfectly and you can see a small change on the screen when you press the menu button, so it has to be something related to display, 'cause everything else is working...
I don't know what to do now...
