@nonameboy I don't have an Rpi4 so I can't test it, but there are no reports of other users with the same problem, and it doesn't make sense to work better on Rpi3 and not work on Rpi4.

What version of Recalbox are you using (say version, don't say "latest")?
Did you build your Recalbox yourself, or download a ready-made image from the internet?
Have you tried with another SD card?
