Sorry should have said, during me trying to trigger the issue like really hard and playing back a video file like 50-80 times.
Well maybe 10-20% of time during normal playback.
If I can press hdmi input button and it brings picture back, guess its livable for now but obviously not ideal.
Anyhow I have posted a new thread here and also posted my logs so hopefully we can find a better fix, it really does feel like a software issue to me but could be wrong.
