Windows 10: my screen glitches out when i play some games and then my cursor just glitches out too

i cant show a picture because when i play the game it only happens when my screen is directly at the gameplay. if i open up a menu or exit out of the game it goes to normal so i cant really get a picture of it. but it just glitches out my screen like crazy.

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

 

mouse glitching out when playing a game

When i play a game like fortnite my mouse glitches out. i tried to play other games like roblox but even that game has the same problem.

(with my mouse glitching out i mean if i go left it freezes for a second midway the game and then it goes further and that's really annoying when i play games)

 

Glitch when playing fullscreen
