Good day 3rohunter,


We understand you'd like to Change Websites preferences in Safari on Mac and recommend looking into the webGL feature to see if that helps with the flashing.


For additional help with Safari, Contact Apple Support.


Thanks for posting on our Apple Support Communities forum.


Take care.
