I've just noticed an amount of screen flocker/interference on my 2015 1.2 MacBook, only when watching videos or running a VM or removing into another computer on RDC.

Has anyone else experienced this?

My 2015 1.1 rMB has also started flickering on videos and certain websites (I notice it on the Apple website - at the top navigation bar when scrolling upwards). However, it doesn't seem to be related to temperature and goes away if I reboot - which makes me more hopeful that it is a software issue rather than an impending hardware failure. I frequently connect to a 4k monitor using the apple AV usb-c hub - I wonder if it could be related to disconnecting without rebooting but haven't been able to notice a pattern yet.

Coincidence. This started happening for me on a 2015 1.2Ghz Macbook about 10 days ago. Happens most often with videos, FaceTime and scrolling, and disappears after a reboot. I use the LG Ultrafine 4K monitor and I've noticed that it tends to start after I've disconnected from that.

I am having this same issue, although I have had it for a few months now. I have even taken it to apple because it, at times is so bad that it's not useable. But of course it doesn't do it at the store. For me it happens when I am connected to my external monitor and when I'm disconnected from it. A restart helps but it always comes back. I have even completely reformatted my computer without a time machine back up...still comes back!

Just signed up to post the same issue. Happened since I got my new Acer H7 Monitor a few days ago. Restart seems to be at best a temporary fix, the moment the unit gets reattached to the Display these glitches pop up again. Seems to affect UI elements which use blurring and dynamic fields like video the most.

Machine: 2015 MacBook 1.1 (10.12.4)

I've got the same problem. I first thought that it was an issue with a dongle (flickering was happening most on external displays. I swapped dongles and the flickering continued. Then, flickering on the Mac screen got worse. I was about to book an appointment with the Genius bar when I saw this thread. Hopefully this is an issue that can be resolved without a Genius bar visit.

I did the EXACT same thing. I switched dongles and the HDMI cable from my external monitor, didn't help at all. My flickering also happens even more when I'm connected to my external monitor.

I'm getting it whether connected to an external monitor or not, although it is more pronounced on the external monitor.
You should not have flickering when the machine has just been rebooted and has not been connected to an external display after said reboot.

I am investigating the issue and will provide Feedback to Apple. Anyone with a 2016 unit causing said glitches?

This appears to be a driver issue since it occurs even when the external display has been removed (I hope, my machine is out of warranty).

I've recently started to experience this on my 2015 model; glad it sounds like a software issue. A reboot helps. Seems to only happen with graphic heavy websites/photo app.

Unfortunately mine has been happening way before the 10.12.4 update. About a week ago I decided to do another factory restore and try out not using the beta software and its been alot better. Then I decided to take a change and re-enroll in the beta program on my MacBook and it still hasn't been AS bad, but it still happens. I should mention that I did not do a full Time Machine restore after my reformat. I just put back my documents that I had put on a thumb drive. I didn't restore any settings or other files. So maybe it was a glitch in those. Who knows...

Hi, here same problem. Using my MacBook 12 (2015) for a year. Just 2 months ago got my LG 4K and after a month the problem started. Also the same issue on a AOC 20" monitor with 1080p.

I have the same problem on a Macbook 12" 2015. After 10.12.4 update flicker started both on the MacBook screen and when using an external monitor via Apple's original USB-c / HDMI/USB/Power adaptor.
Hope this get fixed soon...

Having the same issue, between YouTube and twitch getting a lot of flickering on my MacBook (Retina, 12-inch, Early 2015). Not sure when it started, but it is annoying.

It happened too me while giving a course on a beamer in Visual Studio Code (blue bars) and Safari (tabs, top bar)... I was afraid my macbook's video card was about to call it a day, but luckily it seems like a software issue.

Go to an authorized service provider . You either have a screen or a video card problem . Therefor either your display or logicboard has to be replaced . There are authorized tests that can be done on your laptop.

No it's a software/driver issue. Does not happen in safe mode. Besides, the tests will all be negative once a reboot has been performed and you are then back to where you started once an external display is attached at home.

I did not encounter the problem the last 2 weeks after a reboot and no longer connecting to a beamer. BTW View on the beamer was always okay. So why spend a lot of money replacing hardware?
