This is weird. Haven't seen this issue before. I was editing something on the GM Layer or the Map Layer when this happened. Initially the problem appeared as everything being semi-transparent sort of like in GM Layer mode, except stays like that when I switch to Player mode. I tested and researched the problem. It turns out the Page's Background Color is showing through. Somehow. There is a transparent cast of the page's Background Color that seems to go OVER the layers or some of the layers. It seems like maybe the background color (for me it's a blue ocean color) is on top of the Map Layer, or copied into the map layer. (?) I tried everything possible to select the blue overcast, but it seems to be unselectable. That's when I deduced it's the background color. I changed the background color to Orange and everything turned transparent orange cast. Note: I also logged out of the game & back in, logged in as Player (you'll see a Player view screenshot below). I'm on a Mac in Chrome browser latest version no add-ons. My 3 screenshots are with the blue / ocean background color. The map should normally look more saturated and non-transparent, basically all the colors look wrong. In GM Mode, Note this is "on" Map Layer yet things are transparent as-if I was editing GM layer. Next screenshot is the Player view.... This is where you can confirm that the blue ocean background color is ABOVE the main Background Map on the Map layer, yet it's actually not above everything (like the Rivers) oddly. Last screenshot to show the background color for the Page that I have. What have I done to cause this? How to fix this? As far as I know you can't select or move the background color, as if it were a layer with "To Front" and "To Back". (?)
