Major Issues with Dynamic Lighting

So, I created a new page, dragged my map onto the map layer. I created a token (on the token layer) and gave it the properties of dark vision (as outlined  here ). Everything in the page options was turned off when I started (grid, fog of war, dynamic lighting). Then, I switched the dynamic lighting layer and drew my lines. Then, I went to the page options and turned on Dynamic Lighting, Force Line of Sight, and Restrict Movement.  Now, I can't select the token while on the token layer. I can't move the map when on the map layer. I can't see the dynamic lighting lines I drew while on the dynamic lighting layer. It's like the entire map and everything in it froze. I turned off dynamic lighting and all the other options, refreshed and everything was fine again. What gives?

Hey Mr. Jane! I'm sorry to hear that you're having issues with the site. Could you please carefully work through the first three steps of our guide to Solving Technical Issues ? Step 1: Make sure to use the right browser Please check if these issues persist when using both Chrome and Firefox. Step 2: Ensure that there are no extensions/addons interfering with Roll20 Please disable all add-ons/extensions and anti-virus programs. Step 3: Clear your cache If none of the above succeeds, please thoroughly work through Step 4 . (Don't forget the complete Console Log!) Thank you!

It works just great on Firefox. Never tried Roll20 on there before. The strange this is that I've used Dynamic Lighting on the maps already done that come with Storm King's Thunder and I never had any problems. Should I still go through Step 4 to find out why it would be causing problems in Chrome?

One pretty common problem with dynamic lighting and chrome is that hardware acceleration is required. Could you try  enabling or disabling Chrome's Hardware Accelerations settings ? if that doesn't resolve the issue, go ahead and complete steps 2-4 above.
