Fullscreen video turns pink and green in QuickTime/iTunes

After upgrading my Mac mini 2012 to High Sierra, when I play any video in fullscreen in QuickTime or iTunes, the video colors skew pink and green as if the blue channel is dropped entirely. It happens immediately after I take my hand off the mouse and let the onscreen controls disappear. As soon as I move the mouse again, or if I leave the mouse over the onscreen controls to keep them active, the colors return to normal.

If I use Screen Sharing on another Mac to connect to the Mac mini, the colors return to normal as if Screen Sharing keeps the screen active in the same way that moving the mouse does.

Changing ColorSync profiles does not help. Turning off hardware acceleration or running in safe mode might help, but there is no way to do that in recent versions of QuickTime.

It does not happen in VLC or any web browser.

This seems to be a common issue; see below for links to other questions that seem to describe the same symptoms. Hopefully we can consolidate and get more attention on this.

I have same problem in QuickTime and some movie players in Safari (openload for example), Youtube works fine. This happened after update to High Sierra. VLC works fine! Mac mini late 2014.

It‘s an open thread. You might consider updating your post with a bold DO NOT REPLY so you don’t get pinged with unhelpful replies. Or unsubscribe from notices on it. Sorry to trouble you.

Same problem here with macOS 10.13.2... I can confirm the new bug

Yes similar chip sets can cause analogous problems. I have gone to apple and had them do a hardware check on my mac mini and everything was fine. They concluded from the detailed 15 hour apple care discussion and notes that it is most certainly a software issue. They elevated it to a level 2 issue. They tell me we can expect a patch anywhere from 1-3 months!

It's good news that they elevated the issue. It's bad news that it will take 1–3 months to get a fix.

In the meantime, can you post a case number or some other reference, so that anyone else who finds this thread can mention it if/when they call Apple for themselves? We don't want everyone to go through the same 15-hour process.

Same thing for me. I have a 2012 Mac mini w/ Intel HD 4000 GPU. I figured that a fix would come alone with OS version 10.13.1, but nope. In full screen mode (in iTunes), if I leave the mouse cursor at the bottom of the window (so that it shows the time elapsed bar), the video will play normally. But as soon as the time bar disappears, the greenish tint will display on the video.

There's no way to update a top post, as far as I know, and the only way to close the thread is to click "This solved my question" on a reply. I'm not going to do that until we actually have a solution, and I'm not going to unsubscribe either, so… here we are.

It's nothing personal, your reply just happened to be the most recent. But the fact is that between this thread and the matching one in the QuickTime forum, I've received more than a dozen notifications of pretty much identical reports. They're simply not helpful at this point, not when it's a known bug, and that's what I'm saying. I posted to tell you and everyone else that comes after you.

Would you rather that I didn't say it's a known bug?
