I'm running OS X Mavericks 10.9.1. Some of my Dock icons for running applications, including the Finder icon, now appear blank and empty, or as a square filled with random noise pixels.
I have tried "Verify Disk" in Recovery mode, and it detects no errors. I have Repaired Permissions and rebooted.
Is there some cache to flush or database to rebuild that could fix this seemingly harmless but annoying anomaly?
