Two of my players (one on a Yoga and the other on a Surface Pro 2, both using latest Chrome) experienced dynamic lighting being excessively dark for them yesterday during our session when they were in dim light. Their tokens were giving them vision, but it was extremely dim, to the point that they could not make out anything on the map if it wasn't very close to their token. If I as the DM used Ctrl+L to look from the perspective of one of their tokens, the map was the normal dim light brightness. The game board account I have that I cast to my TV that can see everyone's perspective looked fine as well. The other two players in the party experienced the lighting normally. The two affected players had their laptop displays at maximum brightness.
