Fullscreen youtube colour artefacting.

guppy

I noticed this happening when watching YouTube fullscreen earlier this week. It just occurred again and it caught on to me that it only glitched when f.lux was in effect. Googling around led me here.

I only registered and am posting since I just wanted to confirm that the issue is happening and bump this situation up. This is on Chrome 50 for Mac (on MacBook Pro 15" w/ Retina Display Mid-2014 running OS X El Capitan 10.11.6). If I recall correctly; I also updated f.lux recently, so maybe that could be the issue? I don't watch YouTube videos in fullscreen often so it would have flew past me.

registered just to bump this thread. I have a macbook pro from 2012 running os x el capitan and youtube has been bugging out quite a bit. Are you guys going to get on this at all?

isaachinman

Bumping as well, experienced this issue just moments ago for the first time, after having used Flux for years.

OS:
OSX El Capitan, 10.11.6
Graphics: Intel Iris Pro 1536 MB

Browser:
Google Chrome
Version 53.0.2785.116 (64-bit)

Strangely, mouse events seem to temporarily mitigate the artifacting, but I assume this is also hardware related.

On another note, your Facebook registration (and probably login) is broken, because your Facebook app is still in development mode.

started happening to me with chrome 53 I think. It is not happening in Safari 10.0, shipped with macos Sierra.. which is the only workaround.

it may be pita to debug this one, seems like a video driver issue. I suggest contacting chrome devs, they will have someone with the skills to debug/investigate even though this is probably not their fault as well.

isaachinman

@gberberoglu Ultimately it's webkit, not "chrome devs".

gberberoglu

@isaachinman well only safari uses webkit now, chrome runs the fork called blink. and my safari does not have this issue..

anyhow I've reported this via chrome feedback, but I think it should be more "official", like a f.lux dev opening a ticket to chromium guys.. I'm sure there are some chromium devs using f.lux :)

You don't get this with Safari on Sierra? Interesting. I'm still on El Capitan but I definitely get it with Safari in both youtube and netflix. Looking forward to upgrading to Sierra then

@mixolyd try safari tech preview.. it runs side by side, and works on el capitan.. https://developer.apple.com/safari/technology-preview/

@gberberoglu @mixolyd Cool, good input.

As I said in my original comment, the issue is somehow affected by mouse events. Specifically, (for YouTube at least), if you maintain a hover state (eg go fullscreen and hover over the bottom toolbar, keeping it open for the duration) the artifacting doesn't occur.

That being said, it's a silly workaround. I'm not sure how well-funded Flux is, but it should certainly work with a stable version of Chrome. I've worked with the webkit guys in the past and am happy to help here if someone from Flux can provide some direction.

gberberoglu

ok now I'm sure that this is a browser thing.. safari used to have the problem but the latest safari works..

I downloaded chrome 51 just works without any artefacts but latest 53 have this issue.. so I looked at what is different in about:gpu pages.

for chrome 51 http://pastebin.com/81VZmqca
for chrome 53 http://pastebin.com/za35dbR9

you can diff them using an online diff tool.. one of them must be causing this issue.. so I think this is a legit case that f.lux guys can bring up with chromiun devs.

Just updated to Sierra. I'm definitely still having the issue in Safari, at least with Netflix.

hhhhmmmm

Hi, i just recently got this issue (and i have being using flux for quite a while now) running videos fullscreen, moving the mouse will stop the pixalate on youtube (only on Chrome, on Safari this issue does not happen, so i don't think this is a Intel issue but a Flux issue) and also in Netflix. any solutions yet?

MacBook Pro (13-inch, Mid 2012)
MacOs X 10.11.6
Intel HD Graphics 4000 1536 MB
F.lux 37.7

hhhhmmmm

this extension for chrome will fix the issue.

isaachinman

@hhhhmmmm Going to check out that extension now.

If it works, the flux devs should really take a look at it and just merge it.

Also: this forum template the flux guys are using is awful. Why isn't bug reporting happening via GitHub?

The extension definitely works! Had this issue with Safari and recently thought to switch to watching Netflix on Chrome. Temporary relief. A couple of days ago the same thing started happening . Have just installed the extension and the issue seems to finally be resolved. YUS.

Hi all,

Been following this issue for some time, hoping for a solution to my Mid 2012 MacBook Pros woes.. When it was revealed that the drivers / power saving features of OS X were to blame, I was pretty upset, but pressed forward in Chrome. Happy to say, after upgrading to macOS Sierra, the issue is gone in Safari. I can confirm Chrome 53 also does not have the issue for me, as others have stated.

I would note that I followed the Public Beta upgrade path for Sierra. Not sure if this makes the difference from those who still have issues.

A few more specs for anyone watching:
GT 650M Discrete
HD 4000 Integrated

I'd add to all those still hoping for a fix, if it can work on mine, it can work on yours. I waited so long for this, glad it is finally here. Good luck!

Can still replicate with f.lux 37.7 and Chrome 53.0, but not Safari (10.0). The extension posted above fixes it for Chrome as well. I'm on a 2015 MacBook Air 13" (Intel HD 6000) running Sierra with everything up to date.

Edit: I haven't done any AB tests to confirm it, but I have noticed that my Mac runs hotter and burns through battery a lot faster with the aforementioned extension installed. I guess screwing with Chrome's video rendering path isn't such a great idea.

Gabriel

Having the same issue (Chrome and OSX Sierra). Disabling adblock (ublock) does the trick though. Anybody else noticing this?

megajames

Thanks @hhhhmmmm and @Gabriel, installing that extension and disabling AdBlock seems to have done the trick.

Same problem... this is true for youtube and itunes as well...
