The problem now is that MM is lagging soooo bad at 3840x2160@30 Hz and no matter whether I am using the default modules or some third-party ones… :persevering_face:

If the resolution is lower than everything becomes smoother. but please note that this wasn’t happening with previous Buster revisions!

Now I don’t know where to start from or what to tweak/edit…

Honestly I don’t want to run MM@1080p because this was not the goal for buying a rpi 4 with 4 gigs… :worried_face:

@MichMich or someone else has a clue about what’s going on please?
