We’ve tried to update to 4.0 in the past but encountered some show-stopping issues. Now, months later trying it again the issues are still there.
Video sources flicker, colors shifting every few seconds. Often shifting to red and back to green. This is not on the source video.
Changing scenes seems to be slower and laggy some times taking up to five additional seconds.
Color shifting example. I have example on youtube.
