LibreOffice Impress - glitchy presentation display

users

I recently installed LibreOffice on a new computer and notice that Impress
has white dots diagonally across the screen and also in random places on
the presentation screen. Is there a setting that needs to be changed? BYW
the presentation is fine on another computer.

I run Windows 10 Home 64Bit with 8GB RAM and LibreOffice 5.2.1.2
