I know this was a while a go and Dugi is looking in to updating the Map fog option.
I notice that you are using ElvUI, there’s an addon that does show whole map called ElvUI_FogOfWar found on Curse or Wowup.io app.
To simulate DugiGuides map fog, type in /ec and then click on Plugins by Crackpotx
change the color of the Overlay to R 124 G 124 B 124
Should have #7c7c with A 100
