As I add more icons to my favorites list under the activities button, the list grows as it should until it reaches the bottom of the screen.  It then scrolls down off the screen.  As I keep adding more icons to the list, at some point a smaller set of icons are displayed, but the bottom few, (about 3), icons, plus the bottom grid are missing.  I have trimmed down the list and it returns to normal, but as I add more different icons back, the bottom few are again truncated.  I have removed the file "~/.config/dconf/user" which should hold the favorites list, but the problem still exists.  This feature did work up until a few days, (maybe a week) ago.
