Since updating to 9.0.2 I've noticed when 10s in after starting playback on certain x264 videos I see a brief black screen (for about 1/2 a second) and then video continues to play fine.
These same videos played fine previously and there has been no change to hardware.
Adjust refresh rate on playback is not enabled and I've tried playing around with different resolutions/refresh rates with no joy.
It doesn't happen if I rewind/skip back to the beginning of the video but it always happens at the same time when I start the video afresh.
