I have a Raspberry Pi 4 running LibreELEC. After about an hour (sometimes less) of playback it starts to skip and stutter.
I am using "Sync Playback to Display" because it's connected to an old CRT TV so I want 24 fps content to play back at 25 fps on 50 Hz display (576p50hz)
I have tried different builds of LibreELEC and doing clean installs and I get the same issue every time. Perhaps there is some memory leak or bug in the code for the "Sync Playback to Display" option?
