I've gone through all the troubleshooting and the recent (I believe august 19th?) update's webgl related error is a huge annoyance. Like some have suggested, opposed to the advice about enabling hardware accel, I've had to disable it for the virtual tabletop to work. It's somehow related to the fact that regardless of what I do, chrome offers me ZERO options to utilize webgl when hardware accel it is enabled. At the same time, Firefox is able to run the VTT just fine without compromising my browser settings at all (though I definitely don't want to use firefox).  Nevermind the fact that even if webgl was available to me (yes my drivers are up-to-date), it requires knowledge of adjusting chrome::flags  to bypass the issue. I think it's clear that roll20 needs to get on top of this problem asap, because it's definitely gonna turn some people off when they run into a roadblock that hard stops them from even using the vtt on a popular browser like chrome without jumping through hoops on the forums to figure out why. I ran into this problem for the first time on game day and was saved only by the fact that firefox worked (and I'm the dm X_X).
