New Dell Monitor Showing Pixel Issues During Fast Screen Operations

I recently purchased a Dell monitor that is still under warranty. However, I’ve noticed that some pixels die and then return when I perform fast actions on the screen, such as rapidly opening and closing tabs. I don't believe this issue is related to my graphics card, as I use an NVIDIA GeForce RTX 3060 Ti and have no issues with lag. The screen itself seems to be functioning without any lag. I suspect the problem might be with the monitor. I would appreciate it if Dell could get in touch to resolve this issue.
