     Safari: Bug not present (Version 9.1 (11601.5.17.1) Mac)
 

What steps will reproduce the problem?
(1) Watch YouTube video on external display

What is the expected result?
No flicker

What happens instead?
Random bright flickers while playing the video, there doesn't seem to be any pattern to when they happen and rewinding to the same moment does not create the flicker again. It works fine in Safari and also works fine when viewing the video on the Macbook display instead of the external display.
