https://imgur.com/NkNlUOV this is the image of what usually happens. Basically small boxes that are bright and colorful and they usually move around a lot and twitch. Sometimes there are large chunks of these boxes on the screen when it happens. Usually, I rarely get this anymore and it can happen when I play games, especially highly demanding ones. This time though it just happened when i was chilling in discord. I use a laptop (Dell g5se 5505) and its connected to a monitor that has been used with no problem before. When it happens you can see the boxes on the laptop screen and the monitor so I think the problem is the laptop. Plz help
