My dekstop every so often gets a white/grey horizontal bar that shows up on the screen, and I don't know what it is. I have a dual screen and when I mirror the image onto the other screen it shows up on that screen as well. Thus, I don't think it is pixels going out. A reboot fixes the issue but I'm just curious if anyone else has had this problem, and if there is an easier way to fix it than rebooting? Here's an image of my screen below:
