Fullscreen youtube colour artefacting.
-
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 :)

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?

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 . -
I'm still having the same issue in OS X El Capitan Version 10.11.3

@David-Schlachter It seems related to Intel integrated GPUs. Intel/Apple never got around to fixing it on the Intel Mac driver.
-
What @benfowler said works. Which is mystifying... Anyone has any idea why showing the controls would affect the refresh rate or any other aspect of rendering?
Also @f-lux-team: have you considered open-sourcing this project? Someone who's affected and with some coding chops might be able to give more debug info and maybe even submit a patch?
Thanks for the great work and for looking into this issue.
-
@shariffy The bug is not in f.lux, it's in the OS video driver. Open-sourcing would do nothing.

@lorna Fair enough. Just a wild thought as this is both a long-standing issue and affecting quite a few users.
@innerbat I am aware. That said, I doubt Intel and Apple are falling over themselves to fix the issue. My thought was to research how f.lux could detect when the glitch will happen and (offer to) disable itself in those problematic cases. Research which could be easier with access to the code. But thanks for shooting down a benign suggestion within a minute of posting. :) Here's your sticker.

just to give an update: I still have the same problem with OSX 10.11.4, Safari 9.1 and flux 36.6. Btw moving the mouse does prevent the artefacts from happening, but who wants to do that all the time in fullscreen right? ;)
-
@lorna any word from the intel guys on this? thanks!

Hello! I'm having the same problem with artefacting, but in quicktime. If a spot in the video is pure white, and the video is playing with the cursor hidden, then white spots are not tinted, rather pure white. You can see when I start playing the video that the colors brighter on the GIF here.

is anything being done about this or should i just uninstall f.lux?

This used to be a deal breaker for me too but the workaround suggested by @benfowler is perfect and currently the most convenient way to avoid the issue.

@jonsnow When you do that, you are not really in full screen any more, because the video title appears so does the video timeline scroll bar, taking up 10% of the top and 10% of the bottom and adding distractions.
-
I'm experiencing the same issues with fullscreen YouTube videos, I found if you zoom in (cmd, +) it removes/stops the artifacting so you don't need to keep your curser on the timeline blocking some of the video, it doesn't effect the video just makes the playback elements larger. No idea why this works or if it helps with netflix.
