Hi,
so I upgraded my Pi3 from Jarvis to Kryton (7.95.3) Dirty this week. I came to rely on the 2 Features "adjust display refresh rate to match video" and "sync playback to display" in Combination with Adjust PLL set to "Max" in System Settings. I've used that combination on Jarvis and it was great, the "err" Value moved slowly to 0 and stayed there, exactly like it was described here OpenELEC Testbuilds for RaspberryPi Part 3 (Kodi 14.0)
On Krypton it does work but I'm noticing a lot more fluctuation, the A/V needs a few Seconds to get in Sync but has to be adjusted far more often because it will drop to -80ms or something like that randomly. Did this change somehow in any way?
