Strange black box when cycling through tables in Pinball Popper

[jerryrs]

I'm new here so I apologize if this is a dumb question. I have my pinup popper working and it launches tables as expected however when cycling through games I occasionally get this weird black box on the playfield preview screen. I'm pretty sure its due to a loss of focus as if i click with my mouse it goes away. Is there anyway I can prevent this from happening because its quite annoying. I already checked that vpx is running in full screen mode. This issue appears to be with pinup popper itself.

I was finally able to fix this issue. 

PinUp Popper Setup/Games Manager/Popper Setup

Screens/Theme

Changed Mode for Playfield from "ForceBack" to "show"

Save Pup-Pack
