Occasionally, my desktop background image will disappear and be replaced with a standard blue screen. The only fix I currently know of is to either pick another image to set as the background, or reset my computer. It also happens (sometimes) when I attempt to open an application as an administrator and at the prompt that asks "Do you want to allow this app to make changes to this device," the background image disappears.
I saw this question, but it's for Windows XP, and it also appears to be happening to them only when they try setting a background. I tried refreshing the desktop, but the image did not restore.
My graphics driver is up to date. I have two monitors, one 4k one as my main display, and a smaller 1080p one as my secondary. Is there a system setting that can be altered that may be doing this?
