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

This also happens to me but, I have the Intel HD 4000 graphics card. My macbook pro is a mid 2012. I'm also running the current version of Yosemite and Safari.

+1 for this. see it all the time when watching videos on my 2015 MacBook Air with Intel HD Graphics 6000. certain patches pixels become very bright for some reason. seems to only happen with moving video, never with pictures or regular UI. weird stuff!

Same problem on MBA 2014 ;/ 10.10.5 / Youtube full screen only

This happens on the new MacBook with the Retina display (Intel HD Graphics 5300 1536 MB), as well.

It happens with full screen HTML5 video (so YouTube, Netflix, Twitch on Safari) when nothing else is displayed on the screen (e.g. it doesn't happen when video controls are visible). It does not happen in full screen videos in Chrome's flash player in the same scenario.

It happens in Quicktime when playing a video downloaded from YouTube. It does not happen when playing the same video with VLC.

I think a common pattern might be retina displays – it seems to me that videos look a little sharper in Quicktime and Safari than they do in VLC and Chrome. Perhaps there is a boundary sharpening filter that's supposed to make things look better on the retina display that messes with however flux works?

Thanks for the additional info. We're trying to track it down and get it reported to the right place for a fix (it probably isn't happening in f.lux, it is just extremely visible with f.lux running).

Current challenge: Can anyone repeat this in Chrome browser?

We have reported this issue to Apple.

I suspect it has been a bug in the Intel decoder for some time, and it's just that we are seeing more paths in the OS that use the fully hardware-accelerated path.

Currently we are seeing this on HD5000 and Iris (HD6000, etc.) It does not happen for us with HD4000 or NVIDIA.

If this goes on for a while, we might be able to make f.lux force the hardware acceleration off, but we'd really prefer not to do that because of battery life/etc.

I have the same problem on my MacBook Pro (Retina, 15-inch, Mid 2015) with Intel Iris Pro 1536 MB.

The problem appears exactly as described by other users.

lorna

Thanks @AnMartini hopefully the right people will be able to fix it soon.

Same problem here with MacBook Pro (13-inch, Mid 2012) and Intel HD Graphics 4000 1024 MB

OS X Yosemite 10.10.5
Safari 8.0.8
f.lux 36.3

I came to this forum to report the same issue... but it seems I'm not alone! I have a MacBook Pro (Retina, 13-inch, Late 2013) with a Intel Iris 1536 MB and my issue is exactly same as described above.

I am currently running 10.11 Public Beta 15A278b and I can confirm the issue is not resolved.

edit: I can also confirm issue is present is safari and quicktime, but not chrome and VLC. must be related to some video hardware decoding apple apps are able to take advantage of third party ones aren't?

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.

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.

rouadec

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).

Auty

@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?
