Noticed when playing video If I try to add a bookmark a chapter the system hangs slightly the video and audio gets out of sync .. once that menu is closed it seems to all catch up.
Just odd with the spec of the kit I didn't expect it to suffer, oddly enough my old Pi 3 copes fines.
Got 4GB Rock pi 4 running - LibreELEC (Leia) 9.0.1 MR
Also pressing STOP on a video seems to take a couple of seconds to stop the video ???
