It's not a big deal, but I used to just hit "play" on any video file (Access is throught SMB, on a Mi Box over the LAN, but that's not the issue) and it worked like a charm after 1 second or so,
Now, it loads (black screen) for like 2-3 second, then like a wierd glitched screen (or sometimes plain green screen) for very very short period, like 0.1 seconds, and then it starts the video.
Same thing when I try to close the video and return to the previus menu.
Pretty sure it started when I upgraded to the latest Mi Box firmware (or android firmware, not sure if there's a difference)
Thank you. I'm not even looking for a fix, just wanted to know what causes this out of the blue.
Edit:
Can it be related to the refresh rate changes? as mentioned here:

It's your TV's refresh rate changing to match the file. If your TV has a info button press that and it should show your current resolution and refresh rate.
