Maps Not Effective on Some Maps

[Davorious]

My players have reported to me that the mask is not always effective. We are currently playing the "Hidden Shrine of Tamoachan". One the player's maps, you can see the outline of the rooms. I have included a copy of a screenshot from one of my players.

Is anyone else having this issue?

This is known issue. Not really a good solution to it. Depending upon zoom level of the players it may or may not be present. If I remember correctly, if you do not use a black background on your map null areas then it is less likely to happen.

This has been reported many times. One of the best threads discussing it is here (https://www.fantasygrounds.com/forums/showthread.php?25950-Fog-of-War-**BROKEN**).
