Screen not repainting

[ToddAndMargo]

Hi All,

FC23
Xfce 4.12

Whenever I come log into my GUI or come back from screen saver, my 
screen does not repaint. It is all black. Everything is still there, 
just click on it with the mouse and the item you hit will repaint. Mouse 
across the task bar repaints those items too. Once repainted, they stay 
repainted.

This happened coincident with a "dnf upgrade"

Any idea how to get normal behavior back?

Many thanks,
-T
