Fullscreen youtube colour artefacting.

episer

Would like to give a heads-up and also looking forward to hear an update (especially back from Intel!). Just noticed this bug a few days ago. Exactly the same experience as above. Reproducible with white videos on Safari, but not on Chrome.

Macbook Pro mid 2014
OS X 10.10.5
Safari 9.0
Flux 36.3

Same problem here.

When playing fullscreen video in iTunes I can make the artefacts disappear by moving the cursor, this will make the video controls appear (still fullscreen), when I stop moving the cursor, as soon as the video controls disappear the artefacts are back.

Flux 36.4
OSX 10.11 (15A284)
MacBook Pro (Retina, 13-inch, Late 2013)
Intel Iris 1536 MB

@lorna It's been two months now since you guys reported this issue. Any kind of update yet? It's not just youtube. It's all fullscreen video.

Made this post some days ago https://justgetflux.com/forum/topic/416/f-lux-glitching-youtube-in-safari ,didn't found the current post earlier.

Been experiencing it since OSX 10.11 too.

Just with Safari, Chrome works fine.

Happened with Netflix too last night. :( Please fix this.

episer

Seems it has been fixed since the new update. Thank you!

The update doesn't seem to have fixed the problem for me. Just tested fullscreen quicktime and fullscreen Netflix in Safari after updating to 36.5. Restarted my computer in hopes it would work, but no luck yet.

I have the same issue. The pixelated maxed-out bright spots occur only in fullscreen videos in Safari with no HUD. Evidence here.

MacBook Pro (Retina, Mid 2012)
Intel HD Graphics 4000 1536 MB
OS X El Capitan 10.11.1
Safari 9.0.1
f.lux 36.5

No fix with the newest version.
As an addition the problem appears with videos on Kickstarter too.

Same issue here:

MacBook (Retina, 12-inch, Early 2015)
Intel HD Graphics 5300
OS X El Capitan 10.11.1
Safari 9.0.1
f.lux 36.5

PS: Specifically, exactly as Logica Ens above described it, i.e.: "The pixelated maxed-out bright spots occur only in fullscreen videos in Safari with no HUD."

Same issue as above.
MacBook Pro (Retina, 13-inch, Late 2013)
OS X El Capital 10.11.1 (15B42)
Graphics Intel Iris 1536 MB
Happens in Safari Version 9.0.1 (11601.2.7.2)
f.lux 36.5

Happens in fullscreen videos at bright spots. If I wiggle the mouse and the youtube overlay reappears, the problem then disappears. (So the HUD rendering fixes it)

Michael Fisher

As countless others have said, the bright spots appear only in Safari fullscreen with no HUD rendered. I use Safari's default video player and it happens in that.

MacBook Pro Retina (13 inch, Early 2015)
OS X El Capitan 10.11.1
Intel Iris Graphics 6100
Using Safari 9.0.1 and f.lux 36.5

The artefacting happens only when the scaled resolution setting is enabled in System Preferences (the thing that makes the menus etc smaller/bigger)

Logica Ens

@Michael-Fisher The artefacting happens when the default for display resolution setting is enabled in System Preferences too.

Having the exact same problem with;

f.lux version 36.6
OS X 10.11.2
MacBook Pro (13-inch, Mid 2012).

Problem started right away after installing f.lux. I've only tested it on Safari while playing fullscreen YouTube videos with no HUD rendered, it disappears with mouse movement (and as the HUD appears) and re-appears shortly after. It can't be captured with a screenshot (Command-Shift-3), and it looks exactly as Logica Ens captured above.

Also, I can't understand why lorna thinks this could be a problem either with the GPU, Intel video drivers or the Intel hardware. I've never seen this happening before f.lux was installed.

As it seems to happen at different GPUs, OS versions and applications - and only when f.lux is installed; then the only suspect here seems to be f.lux in my humble opinion, and not the opposite. It could be f.lux having a compatibility issue with these suspects, but then shouldn't f.lux be the one trying to solve it...?

Down below are some additional details about my system if it would help.

Thank you!

I believe lorna thinks the problem was already there before f.lux was installed, and that f.lux only exposes the artifacting more.

I can also confirm that this occurs on Safari, Fullscreen Video, no huds on El Capitan with F.lux version 36.6.

I have something to add.

This problem also happens when using a custom calibration preset, in the same conditions (fullscreen, no controls)

Guys, I have Macbook Pro Retina 13 bought in November and I have the same problem but I've spotted it only in Safari in Youtube fullscreen when menu bar hides. Videos from other website seems to be okay. I've downloaded youtube app and in this app everything is okay. I think it is the easiest and quickest solution :)

David Schlachter

I experience this issue on my 2013 MacBook Air, but not on my 2010 MacBook. Both have the same configuration (the 2010 MacBook runs off a clone of the Air's SSD).

I see this is a very old issue and I'm still seeing it, El Capitan 10.11.4, Iris Pro 5200. 7 months out, any word on a resolution?

benfowler

There is 1 easy hack to avoid this issue.

Put the mouse curser onto the youtube / netflix video scroll bar at the bottom of the screen.
The issue seems to arise due to refresh rate at full screen video in safari.
Possibly to save battery, safari technology doesnt refresh areas of the screen that have pixels the dont change or similar.
But when you put the curser over this area, , it does seem to solve the issue .
