Is there a way to refresh the desktop?
I'm running Mojave 10.14.6 on a 2012 iMac and my desktop screen is corrupted with icons showing as sheared or partly duplicated. The background wallpaper is not affected, the dock is not affected but the icons are messed up. If I click on an icon, they briefly all redraw correctly, and then revert to the corrupted appearance. How can I force a redraw without a complete reboot?
