Strange colors/blue-fringed mouse pointer on full-screen YouTube when f.lux is active

Hello, same problem with my

MacBook Pro Retina late 2013
Intel Iris 1536 MB

Areas of images with the same colour seem like they're getting heavy codec-compression.

Issue occurs with video playback both in VLC and over web browsers.

Macbook Pro Retina Mid 2012
Intel HD Graphics 4000
Yosemite 10.10.5
Safari 8.0.8
f.lux 36.3

Get artifacting on "bright" areas of video when in fullscreen of youtube. what's strange is that if I watch the video not in fullscreen the artifacting isn't there. Even stranger is that if I wiggle the mouse while watching a video so that the timeline shows the artifacting will go away temporarily while in fullscreen video. but once the timeline bar disappears it comes back.

if I force the graphics card to change to the discrete card (Nvidia GeForce GT 650M) there is no artifacting at all. So it must be with the discrete graphics card.

I also get the artifacting when watching videos on Vimeo in Safari, even when not on fullscreen.

I too have the same problem. I'm running:

MacBook Pro (Retina, 15-inch, Mid 2014)
Intel Iris Pro 1536 MB
f.lux 36.3.

Weird colours and artifacts as described by others in the thread on full screen YouTube when there are no play controls showing. Weird that it doesn't also happen when the video plays in a window. I have noticed the problem in fullscreen quicktime too.

Exactly the same issue, I now leave my mouse cursor on youtube pause button on fullscreen to avoid it.

Twitch.tv does the same too, but you can move the button bar just below the screen and hide your mouse cursor there

MacBook Pro (Retina, 13-inch, End 2014)
Intel Iris Pro 1536 MB
f.lux 36.3.

What we're seeing is this is due to the integrated card from Intel, so:

Some people may be able to fix this by locking the discrete card (via http://gfx.io) and using that for video.

We are noticing that if a video is re-encoded with Quicktime the problem does not appear, but Youtube and Netflix appear to have "out of gamut" video that presents this overflow.

For everyone with a single Intel card, we may be able to do a workaround by drawing a tiny transparent icon over the corner and preventing full hardware acceleration, but I avoid hacks like this until everything else fails!

Happening on MacBook (Retina, 12-inch, Early 2015)
using Intel HD Graphics 5300 1536 MB

Since it only has a single Intel card, would you be able to provide a workaround for people like me?

Thanks for making f.lux!

Is anyone still seeing this on 10.11? Our test machine is showing that it has improved the problem considerably (sometimes there is still a strange blue glow).

@lorna I still see the same blue glow and its still quite distracting.

seajay

@lorna Definitely not fixed in newest released update. Also, is there a way to update from within flux or do we have to check for new updates periodically, then download and replace the old version?

lorna

@seajay We have autoupdates but we only push them when we know they are ready to go, so the download link at justgetflux.com will always be up to date. So 36.4 is the most updated one, but it hasn't had any change to the video (this is all on Intel). So if you've updated to OS X 10.11 you may see some improvements.

seajay

@lorna got it. well, I'm on OSX 10.11.1 and flux 36.4 and am not seeing any improvements. :(

lorna

OK good to know, thank you! They fixed the awful bug that was in darkroom and basically couldn't reproduce the other bug with blue everywhere - there was an improvement on my Macbook Air but it wasn't fully gone. Is there any specific content you can send us (ok to send me a chat) that it always happens on?

seajay

@lorna It always happens on this YouTube video. (sfw) https://www.youtube.com/watch?v=Iqxbbiuqvag

seajay

@lorna oh wait I guess I'm referring to the artifacting and not the blue mouse. I don't notice the blue mouse problem here on this video. should I move my video suggestion thing to another thread that's more about artifacting?

lorna

No, this is fine for the artifacting trouble. Thanks for the video! (I'm not sure Apple would love having us submit this as the example ha!)

seajay

@lorna Hahaha yeah, it's just one that I was watching for a research paper and kept getting the artifacting problems.

seajay

@lorna okay yeah so this video every time gives artifacting as well as the blue mouse bug.

This is quite frustrating. I prefer Safari because of the interface and how efficient it seems to be; watching a video in Chrome or Firefox uses up about 70% CPU whereas it is barely noticeable in Safari.

Flash-based videos are fine but Youtube Center no longer lets me force the player type so I'm basically stuck using a non-preferred browser if I still want to use flux.

First-world problems I know but still frustrating.

dsquareddan

updated to El Capitan 10.11.1, the issue still persists. Guess I'll be disabling f.lux when I need to watch fullscreen videos at nighttime. sigh

bash

@dsquareddan I am also doing the same. But it is getting tedious to always do so, when I watch a series of tutorials in a row. Any luck fixing this?
