Safari Full Screen Video Problems
It seems Safari applies some sort of post processing to full screen videos and it's causing a variety of color/brightness/contrast glitches on my MBP. All of the problems below only occurs when a video is playing full screen, after the toolbar & mouse pointer disappears.
When using the MBP's internal display:
Netflix: all videos when full screen with caption: brightness changes slightly whenever a new caption appears/disappears. This is noticeable on low brightness. For a select few videos, the entire screen flashes black when caption changes instead of the slight brightness change.
Apparently this has been brought up on the Internet for years but we still don't have an official fix: safari netflix caption flickering
(solutions includes switching to discrete graphics, but I don't have one on the MBP13. And Chrome only delivers 720p for Netflix as opposed to 1080p on Safari, so I guess the answer is to get Windows for proper Netflix?)
When using an external monitor with the MBP in closed clamshell mode:
Youtube: most videos are fine but for some: contrast is significantly increased as soon as the toolbar disappears in full screen obscuring the dark part of the video.
For those same videos, a more obvious glitch happens when night shift is turned on: the whole screen is covered in a red tint. Here's a link to the video where it definitely happens: https://youtu.be/5nLWTVTwOhY

(the tint is actually more pronounced than shown because the camera auto corrects colors using human skin)
Again, all those problems happens only in full screen. I'm looking for a way to turn off this post-processing and get how the videos should appear when they are inside a tab - but in full screen. IMO Safari is a better browser in so many ways. It's a shame that this bug is forcing me to Chrome whenever I need to watch a video.
