What doesn't work: I moved my Third Monitor to the HDMI port on my Mini...still didn't work, Screen Recording still in effect doing it's thing.

What works: Use Google Chrome>Enable Location for the Hulu's of the world>Disable Hardware Acceleration on Chrome.

I don't think there is a similar "Hardware Acceleration" equivalent in Safari.

Using Chrome with hardware acceleration disabled fixed this issue for me.
