glitching screen and glitching videos

Hello,

Recently my laptop screen started to freckle\glitch while playing videos either on the internet or on my laptop so I followed steps suggested as to uninstall and re-install the graphics update however, it happened again not so long after I did that (1 day later) and I fixed the display and so it stopped but the videos appear to be glitched? like I could see the RGB (there is a color stroke that appears ONLY while watching videos and I tried to take a screenshot and while trying to trim the photo I found it looking normal so it's only via videos

I'm using HP ENVY Laptop - DESKTOP -LUQEG7V

Here's a quick laundry list:

List of software to use for overclocking and testing
Examples:
Wattman (and how to find and use it, like an overview, including profiles)
Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)
