Strange colors/blue-fringed mouse pointer on full-screen YouTube when f.lux is active
MacBookPro 9,2 Intel HD Graphics 4000, OS X 10.10.3, Safari 8.0.6, f.lux 34.0
When f.lux is active i.e. after sunset and I watch a YouTube video fullscreen, highlights appear "blown out" and render in strange colors (e.g. very bright pale magenta) and the mouse cursor has a blue fringe around it.
MacBookPro 11,1, Intel Iris 5100, OSX 10.10.4, Safari 8.0.5, flux 34.3
Seconded, happens on Youtube and Netflix both (maybe more, haven't tested). Happens only fullscreen once my mouse fades away, and once I jiggle the mouse the blown out artifacts disappear... until my mouse fades out again. No issue with Chrome, just Safari.

We have had many reports of this on Intel Iris (the drivers have always seemed to mess with video color settings), but the issue with HD4000 is new.
Does the driver have any video-specific color settings that you can see?
Where would I check that?
I'm seeing the same on my Air since as long as I can remember (fullscreen only):

Happens me in QuickTime too.
"and once I jiggle the mouse the blown out artifacts disappear... until my mouse fades out again"
second this too
this happens to me too. macbook air early 2015. This is a huge problem needs to be solved ASAP. i'll be waiting for a fix notification email. till then i'll stick to disabled mode. thank you for your caring
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.

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
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.
Macbook Pro Retina Mid 2012
Intel HD Graphics 4000
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
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.
