    That usually indicates there is a problem with the graphics drivers.

    Go to the support page for your PC on the manufacturers website, then from there, download and re-install (not update) the version of graphics drivers they provide, then restart (not shut down) your PC and check if that resolves the problem.

    2

    If that does not resolve the problem.

    Open File Explorer, then paste this into the address bar and press Enter.

    %AppData%\Microsoft\Windows\Themes

    In the resulting folder, delete the Transcodedwallpaper file(s) and also delete the contents of the CachedFiles folder

    Restart (not shut down) your PC and set your preferred desktop wallpaper.
