After update - screen fonts and colors not complete

[packzap]

After a Linux Lite update in the past week, or so, all the screen fonts and colors do not render properly.  For example, when I bring up Gmail in the browser the red color in the middle of the big "M" does not show.  And the fonts on the desktop and screen have strange distortions on some letters.  Screenshot attached.

I tried switching the font from Roboto regular to Sans regular, but that does not help.  Thanks for any clues.
