So somehow i guess i fixed the glitch thing, (btw im having ps4 standard ,not the slim one), i went for video output settings in ps4 and if you set the settings on 720p its good, on 1080i graphics are awful. I will test out that thing with sharpness in tv settings. Try this one in ps4 settings, its worth it, theres no big difference between automatic settings and 720p.Guys I'm getting the same thing. I have two options for you. If you turn HDR option in PS4 video settings, glitch is gone but graphics is all washed up. Or you can also lower "sharpness" setting of your TV and glitch is almost invisible.
I think it has something to do with a combination for PS4 slim and 4K Samsung TV that supports some basic HDR (2016 series). If you find a better solution please send me a message.
Thx btw
