Fullscreen youtube colour artefacting.

antonis111

@antonis111 Well, this flashing (or flickering) I reported in my posts above, it has nothing to do with flux! It is just more obvious when flux is running, but it is still happening without flux. I contacted netflix and they told me that there is a problem in how the video card processes resolution in Netflix in some MacBooks and Apple must update the drivers. Therefore, I suppose that Apple has two things to correct: both the flickering and the colour artefacts.

Hey all,

A Safari extension, like the Chrome extension, has been requested above... It already exists, it's just not in the "Safari Extension Store" (or whatever it's called) yet.

If you check the github page of the Chrome extension project, it actually links to a signed VideoFixer.safariextz under Releases.
Just download it and drag it onto Safari. It works for me.

From the README: "The Safari extension has been submitted to Apple and hopefully will be available soon."
I'm guessing the review didn't go through..? Maybe a missing icon ;)

Aaaand just for the record, I'm not the creator of, nor do I have any relations to, this/these extensions.
All props goes to C Lundie.

@afabian Thanks for the analysis of the extension

For those of you that don't want to deal with a browser extension, you can just make a "bookmarklet" that will work in any browser.

Go to the bookmark manager and create a new bookmark. Name it whatever you want and set the URL to this:
javascript:document.head.appendChild(document.createElement("style")).appendChild(document.createTextNode("video {opacity: .996;}"));

Then you can go to whatever website to stream, and just click the bookmark before going fullscreen.

Hi all!
Just confirming what everyone here is experiencing. I'm having the same issues on Netflix and YouTube in fullscreen mode. Haven't tried other browsers yet, working on Chrome now.
Subscribing for more updates on this subject, because it's really annoying.

OS: macOS Sierra

Noticed this on mavericks a while ago, but then it went away! Recently updated to sierra and the problem is back :( my MacBook is a 2013 retina, for a long period of time the computer didnt show the pixelated problem.

Im not 100% sure about this but I believe using "clicktoflash" which is no longer available, which forced youtube to use flash instead of HTML5 player stopped the issue, but I've just tested it now and they've updated it and its still showing the same issue, flash or HTML5. Quicktime player does the same but I believe VLC works fine.

Might try some of your suggestions here, but this is a long thread! Has anyone concluded this is Apple's issue or F.lux's? thanks

I just toggled my display colour (in the system preferences list) and it doesn't pixelate anymore! worked! :)

I don't understand why Flux can't fix this.

gberberoglu

@dogduty because it's not flux, it is the Apple who needs to fix it. https://forum.justgetflux.com/topic/213/fullscreen-youtube-colour-artefacting/123

Night Shift is now confirmed in the new mac OS developer version so Apple is clearly screwing with flux

Just to re-iterate the solution on Chrome:

Download the Stylebot extension
Open the Stylebot options
Go to Style > Edit Global Style Sheet
Enter the following:

video {
    opacity: 0.996;
}

For some reason, showing the app at a very small transparency fixes this. You will not actually be able to perceive the partial transparency, but it'll fix the problem :)

I found something interesting.

3 days ago, on feb 2nd. I ran the update "Security update 2016-007, v 10.10.05" which also updated Safari to v. 10.0.3. (Yes I know i'm late on the updates...)

I DID NOT HAVE THESE GRAPHIC PROBLEMS UNTIL I RAN THOSE UPDATES

I guess I had Safari v. 10.0.2 before I updated.
Perhaps downgrading Safari from 10.0.3 to 10.0.2 or older will fix this? I don't know how to do that, but it might be worth giving it a shot. I hope someone will be able to try it so I will monitor this thread closely.

Fyi: I'm running OS X Yosemite 10.10.5 and Safari 10.0.3 on a 15" MBP Retina mid 2015.

@bldgr Doubt it pal. I've had this issue on mavericks, With safari 9 I believe. I thought mine fixed after i did something suggested on here but it came back a few days later. Its been on and off for 3 years now.

@.C.J.W. just to confirm the problem came back. :(

This wasn't a problem on my old MBP (I think it was late 2011), but I'm experiencing problem for a month now since I installed it on MacBook Air (early 2015).

Fun fact/temporary fix :

If you pinch to zoom on the fullscreen video, the artifacts are gone. I now watch all my videos slightly zoomed in. (also works with the cmd+"scroll" zoom if enabled in preferences/accessibility, which is a system-wide zoom)
If you move your mouse to the top of the screen in order for the status bar to show up, the problem disappears as well as long as the status bar is displayed.

Basically, as soon as your mac has something more to do than just displaying a fullscreen video, it all works fine.

I've had this problem since I've started using f.lux a year or two ago and I know that f.lux can't do anything to solve it, this is just some sort of useful hack for when it really isn't bearable. (I'm currently using a 2015 13' macbook pro retina with Intel Iris Graphics 6100 1536 Mo)

This fixes it for Safari but is it ok to use despite its permissions?

Hi, I'm own the newest Mac book Pro 13 inch with Touchbar and I'm running 10.12.3 and the latest version of flux.
I seem to have the same problem of color distortions when streaming from sites like youtube or Netflix.
My problem also occurs when I'm not in full screen. It occurs both in Safari and Chrome!
This is what it looks like. So is it flux's fault or a problem with apple?

Also I haven't noticed the problem when playing a video file with VLC or similar -- just from streaming.

@bliblibli don't worry. Apple is about to release there own solution to blue light in the next point release of macOS. We will not have to deal with this much longer.

@bliblibli This is an Apple bug. We have asked them to fix it many times. They have fixed it for Safari in the latest OS version only.

As the other user states they will be releasing a copy of our older work (without permission, credit, or compensation, since that question comes up often), however I'm not so sure you "won't have to deal with it much longer" since it's not really strong enough to be much help on most screens. They apparently copied our settings back before we knew as much as we do now....
