Question Strange pixels/lines appearing on certain apps when no action is happening

[ThatRedMelon]

I have noticed that on certain screens, including Oculus, Minecraft, paint.net and Quixel Bridge that strange white/grey lines or pixels appear when I am not moving my cursor. When I move the cursor over the affected area it disappears but then appears again. I need to know what is causing this and how I can fix it. I have attached an image highlighting the issue to help with support. Thank you.
