Fullscreen youtube colour artefacting.

.C.J.W.

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.

@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.

lorna

@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....

bliblibli

@lorna thanks for the reply. How is it an apple bug? Problem occurs when I use flux.

I'm running the latest os (that is not beta) and the distortion problem still occurs in safari!

That sucks if the copied your work :(

dogduty

Well even if Apples solution is not going to be great I find Flux unusable on a Mac. So it will be better than Flux for me. I've been using the iOS equivalent and it's decent enough.

lorna

@dogduty thanks for sharing your thoughts. I'm not sure what else you are looking for here in the f.lux forum, but let us know if we can be of some assistance.
