Dynamic lighting issue - Mac.

Having tons of issues with dynamic lighting.  I have two somewhat older Macbook Pros.  One is a version behind on OS X and one is up to date, running the latest Chrome on both.  Trying to run one as the player screen and the other as DM. The older Mac, things work pretty well.  On the newer one, I can only scroll in *almost close enough" and then everywhere that has light goes technicolor.  Fractal lines show up and it is a wild spread of colors.  Checked extensions, don't see anything there.  Ideas?

Make sure Use hardware acceleration when available is checked in the settings: I'm running Chrome version 58.0.3029.81 (64-bit) on OS X 10.11.6 on a Mid 2014 MacBook Pro.  I've seen issues when Chrome updates and also when hardware acceleration is off.

I saw it was on when I was trying to debug last night.   Will take another look.

...and today it seemed to work fine.  Weirdness.

Could have been an issue with Chrome. A buddy of mine did some experimentation and found that refreshing tabs in chrome doesn't completely reset them, even on a full refresh. You are better off closing the tab and opening a new one as that starts a fresh process. Give that a try if it happens again and see if it helps.
