It is an artifact of the display driver being used.  A work around might 
be to <CNTRL><ATL>F2 and then <CNTRL><ALT>F1 to refresh the display.

If that works, then the display is not being told to 'wake up' after the 
resume, and you can add an event handler to force it.

However, you may want to upgrade the graphics driver.

What video driver are you using, on which version of Fedora?

Good Luck!
