Broken Pixels?
as you can see on the image,the background has these strange colors. My standard lock-screen background is plain black, but after closing my laptop and reopening it, i get this bizarre pattern. It also happens on open windows, for example when I let my Document Viewer application open, the pattern appears on that window as well.
This really only happens after locking the screen once and it doesn't disappear until I restart/Shutdown my laptop.
Does anyone know why this phenomenon happens and how to fix it?
