Having issues in my game where all players (including GM) get an error about WebGL. After we load in, the screen flashes white and all we see is a completely black map. Even I, as the GM, cannot see anything. Only happens on one particular page. I have disabled all extensions, cleared cache, updated Google Chrome to latest, and turned Hardware Acceleration on/off. I even went as far as disabling certain options in the game. The ONLY way I could get around the issue is to load the players into a separate page, then pull them over to the page I want them on. But that only works about half the time. Step-By-Step Instructions: Just load into the game. Should happen immediately after load.
