I play on Windows 10/Chrome. Game loads fine and everything works, but when I minimize the Chrome window and open it up again the game part of the window is blank (the ads etc are still there.) I get this error:

"An error occured running the Unity content on this page. See your browser JavaScript console for more info. The error was: Uncaught TypeError: Failed to execute 'shaderSource' on 'WebGL2RenderingContext': parameter 1 is not of type 'WebGLShader'."

Anyone have a clue what that's about, or rather if there's some easy fix I can do? I had no problems with the 2017 version of the game.
