MacBook Pro Video Glitches When Full-Screen in Safari

[Ritsuka]

One issue was fixed in 10.14.1, but some more remains when running on Intel GPUs:
1. small h.264 video have weird artefacts in fullscreen
2. random flash of unrelated image when switching from UI + video to video only in fullscreen
3. color changes in fullscreen when only the video is shown.

for me, full screen video glitch is now fixed on mojave latest release

Happy to report no more artifacting in YouTube/Safari with latest Mojave release.

Has anyone else noticed video glitches when watching video full-screen in Safari on Mojave? I have a 2018 MacBook Pro 15" and I'm on the GM of Mojave, but I notice green glitches and other artifacts when playing video. I don't notice this however under Chrome.

It is happening to me on MacBook Pro 13-inch, 2017. When viewing videos in FullScreen using Safari, the screens starts to glitch. I decided to update to Mojave.. and now is the glitch is a whole lot WORSE.

Way around: Use other Browser to watch online videos... I used Chrome and it doesn't happen.

Now after the update when viewing Netflix with subtitles it flickers.

It’s worse for me. Even after clearing the cache.

Using Chrome...

Still happening for me on 10.14.1 - noticing it on Reddit fullscreen videos and others.

It's disgusting now, it's every other minute. Never happened before. Using Chrome

I'm also having this issue with a 2017 15" MBPr (Intel HD 630/Radeon Pro 650, Mojave 10.14.1)... While watching a fullscreen video via the integrated GPU, the screen flickers and jumps from time to time when playing a video on netflix/youtube. While watching a movie thru VLC there are visual artifacts in the middle of the screen - like a bar across which makes a tear.

Did every reset (SMC, PRAM etc.) and nothing helped...

My one year apple warranty is going to expire this month, so it makes me wonder if I should get it replaced. What do you guys think, is this a hardware issue or just a software one?

One of my friends recommended a clean instal of Mojave thru recovery.

It's a software issue, see my previous post on the issues that are still in 10.14.1

VLC issue might be unrelated.

I also did a clean install and that didn’t work.
It’s abvious a Safari problem.

Need to wait for Apple to address this issue.

Can confirm it’s most likely a software issue. Took my MacBook Pro 15” 2018 in to the apple store and a genius had a look at it and I was advised it’s a software issue being looked into.

Not happy about it since it’s been like this since day one of my purchase (release date of the new MacBook Pro).

I really wouldn’t care about the issue, the only thing is, is that it is causing my eyes to strain and give me a headache.

Same here, Netflix vertically flickers when menu/subtitles disappear in Safari on full screen. TUrning off graphic switching works as workaround, but looking forward to a fix...

10.14.1 did not resolve the issue for me.

 

[Einkoro]

Also far worse now under 10.14.1 and Safari for me with netflix subtitles enabled. The image jumps vertically every few seconds stretching off the screen and back.

Do we have an official answer from Apple for the issue? I have had 3 replacement MacBook Pro's all of them having exactly the same issue. As all of you I do NOT want a device which does not work as intended and instead I have to do workarounds and stuff.

Thank you

You can get as many replacements as you want: that won't solve the problem. We need to wait for an OS update with a fix.

Friend of mine has the same issue since upgrading to Mojave on a 2014 MacBook Air... so it's not even just MacBook Pro that are having this issue.

 

[Ritsuka]

The bugs are in the Intel gpu drivers probably. If enable the discrete gpu (if you have one on your Mac) everything works well.

that's true, but I would suspect the issue to occur in other browsers too however if that was the case. But it doesn't appear outside of safari.

 

[gelazari]

The thing is that the glitch appeared on the Apple Diagnostics Test on both Macbook Pros.....

The thing is that the glitch appeared on the Apple Diagnostics Test on both of my Macbook Pros and furthermore, the issue does not appear on colleagues MacBook Pro's with Mojave. How do you explain that?

 

[Danindub]

How does it appear on Apple Diagnostic test, exactly?

Is your friends MacBook the same model as your friends? Are you sure your issue is the same as described in this thread?

Issue described here is universal across number of models and appeared after OS upgrade.

 

[gelazari]

It's exactly the same issue I'm having only on Safari. Issue seems to be universal but I doubt it. Although the MacBook Pro passed the diagnostics test, the glitch appeared during the test. A colleague with a MacBook Pro sitting next to me does not have the issue while on full screen Safari.

 

[Danindub]

Today's update, 10.14.2, issue still persists.

 

[gelazari]

Today's update, 10.14.2, seem to have resolve the issue for me

Still have it after the update. Very strange. How is it possible that it got fixed in your case?

 

[KatPR]

Does anyone has an idea on how to solve this? I’m still having the same problem. And it’s happening while watching Hulu, Netflix or Amazon streaming videos. It’s annoying to be watching something and then seeing a weird tear or glitch all over your video screen.

 

[CPx]

I had weird Netflix full-screen glitching too, but after the 10.14.2 update, it seems ok now from brief testing. This is on a 2018 Macbook Air. What it was doing before the update was it would show an incorrect random frame from time to time. Really weird.
