Windows 10: Pixel lines building up in Various applications.

Hello dears, I have a problem with my laptop which is a ROG STRIX G513, my laptop's details are as follows: 15.6", AMD Ryzen 7-5800H, NVIDIA GeForce RTX 3060 6 GB, 1 TB PCIe NVMe M.2 SSD, VR. to be exact its name is "ROG Strix G15 G513 G513QM-ES74". I have a weird problem that pops up with certain applications and sometimes games. i will attach a file so you can see the problem for yourself, the problem doesnt appear right away, it sort of builds up each time i hover over a clickable figure or button. each time i do that the lines grow longer. I have checked an another thread on this website

Line of pixels on startup preventing windows to boot

Yes I've tried both suggested steps. Unfortunatly the problem is still there. It doesn't happen as often as before, more like 50/50. But when the pixel line is there, my pc does not boot up anymore. First when I waited for a while, it did boot up. But
now it's just a black screen and nothing happens.

How to remove the line in taskbar under running applications?

I'd like to remove the line displayed under running apps in the taskbar, this:




For everyone who uses non-combined labeled apps this is super annoying, especially on dark theme.
There was a long thread here but the solution presented only works for windows build 1609.
Some also suggested to simply set up monitor to hide those 2-3 pixels, but that would be a problem for using certain apps.

Is there a currently working solution to remove it? Or maybe a color code to make it darker?
