Green blue red dots on screen (MacBook Pro 13 m1)

Hi community. I was using Final Cut Pro and noticed that there were a lot of green, red, blue dots on where the preview is located.

I opened up a file with solid black to check if there were another area with a lots of those dots.

unfortunately, there was another area with dots but it is smaller.

These dots seem disappear or blended in colors while I am watching videos or playing games. But they look visible on black background.

any solutions for this? I found a thread and it says, try resetting NVRAM. But NVRAM reset is not available on Apple silicon computers.

solutions?
