Fullscreen youtube colour artefacting.

@ThatLiamAnthony Where did you know that it's only software problem?

Have you not read any of the replies in this very thread? The issue is fixed by software. Why would it be a hardware problem? This has been an issue ever since Yosemite came out with new video drivers which have this bug

Btw I can't believe you got a replacement Macbook for this... That's hilarious. You could've easily googled and found that it's because of Flux

this looks like a intel hd gpu driver problem, not related to hardware OR flux app itself. Any monitor calibration that uses below 6500K standard temp will hit this issue.

You can try other flux-like apps or you can use built-in monitor calbiration app.. see the image below. you'll hit the same isseu with full screen videos in google chrome.

In my mac, safari has no issues.. so It may be related to the way that google chrome decodes the videos.. open google chrome and type chrome://gpu/ to the address bar, you'll see already there are lots of "driver bug workarounds"..

this is why I think chrome devs (assuming apple won't care since it does not happen in safari for me) are the people that needs to look at it..

@gberberoglu I don't use chrome at all. It does happens to me on Safari.

I'm having this same problem while using Netflix in CHROME.

Same problem for MacBookPro Retina 2016 for any video on Chrome and Safari.

In conclusion any solution?

HI guys, I have had the same issue, in both Safari and Chrome and in multiple video players.
I discovered that my problem lied in the Display Settings. I preferred the Rec. ITU-R BT.2020-1 Display Colour and used it instead of the default Color LCD.
So, basicall, I just switched it back to its original setting - Color LCD - and I am not having the issue anymore.
How to do this?
System Preferences -> Displays -> Color -> Display profile (Select Color LCD).

Hope this solves your guys' issue.

I made an extension in safari similar to the chrome fix. I don't have a a certificate, so it has to be re-activated if you restart safari.

Also, switching to the Color LCD profile did not work for me.

I am using a Macbook pro 2015 13.3'' (operating system: El Capitan 10.11.6). I was watching fullscreen Netflix (I am using the second streaming plan with two screens and HD) on safari at night (colour temperature 1900K), and many times the screen became momentarily more white, like the flash of a camera. At first, I thought that this was in my imagination or was not an artefact but part of the film, but when I quit the fullscreen mode, this "flash" stopped. This problem wasn't too serious, but it was quite annoying some times and I had to stop watching in fullscreen mode. I checked Chrome and this "flash" was also there, but there were also colour artefacts in bright colours. In Chrome, it was impossible to watch in fullscreen mode. These colour artefacts were not in safari.
I searched google and I found this thread and I just wanted to tell my experience. I hope that an official update (an update from flux or apple) will be released soon. Some user in another post reported that this problem exists in macbook pro 2016 (aka macos sierra), therefore there is no meaning in updating to macos sierra yet.

PS: Maybe this "flashing" is a different issue than the colour artefacts that other people are reporting...

@antonis111 Were the white parts kind of pixelated looking? It sounds like you're talking about the same issue we are all experiencing. It only happens on fullscreen after the mouse goes away. I can put the extension files for the safari fix online for people to install on safari themselves.

@mango_ hi not pixelated. The whole screen changed momentarily color. At first, I thought that this was happening when flux was dropping gradually the color temperature but was also happening when the color temperature was steady at 1900K. It was like “flashing” of a camera, but much milder. Or like when the tv is playing in a dark room and the scene changes from a dark to a bright one. In this case, you can see that the room becomes brighter and understand that the scene changed even if you are not looking at the tv screen.
Maybe this was happening because flux disactivated itself for a second, the color temperature rose and then activated itself again?
The pixelated artefacts were only in chrome, not in safari. But chrome had also this flashing issue.

antonis111

Update: In MacOS sierra there are also pixelated artefacts in safari! That's a pity...

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.

hansdude

@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

ITU-R BT.2020-1

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
