Lately whenever I try to watch a movie on my Raspberry Pi 4 running LibreELEC 12.0.2, approx. 10 times per movie the screen will briefly go blank, often for only a split second but sometimes up to 2 seconds, before continuing the movie as normal.
It doesn't seem to cause any major crashes, so I'm not sure if this would show up on debug logs, but if it would I am happy to fetch them.
Any ideas what might be happening?
