Screen flickering issue with full screen videos on safari after updating to Monterey

Hello Everyone.

Fixed: From "Accessibility->Display->Cursor" I changed the cursor size to large and then back to normal. This might be the stupidest solution I have ever seen, how is it even relevant? Anyways I'm glad it worked, thumbs up!

Try This.

Accessibility->Display->Cursor" I changed the cursor size to large and then back to normal.

I may have figured it out! There is no more ‘energy saver’ feature in prefs, so after digging around online, it seemed that the ‘displays-> uncheck ‘try-tone’ box. That seemed to help.

Also update your OS; this seems to be a bug.

thx!

Hello Michael,

I have same issue with my MacBook Pro 16 (2019) with i9 and Radeon Pro 5500M 8 GB. It happens with Youtube and Netflix if I run them with full screen. With Netflix I noticed, it flickers when subtitle shows the next text.

I've just tried as suggested to run with safe mode. There were no flickering. So now what?

I don't think it is site specific since there were no flickering with Big Sure, I got that problem since Monterey update. I also noticed, this flickering only occurs on second screen (Samsung C49HG9x) connected with CalDigit TS3 Plus+ and with DisplayPort.

Best regards

thedoctor47,

Thanks for the further details. It may be this issue is site specific and caused by the way these videos are encoded and streamed since it doesn't happen with local video files. Let's see if there is any change when you use Safari and your Mac in safe mode: How to use safe mode on your Mac.

Let us know what happens.

Cheers,

Unfortunately they didn't say anything yet. So I'm not sure if they're reading this thread?

Today I found out, the screen was also flickering when I run Windows (with Parallels) fullscreen on external display. There were no video, just Windows Desktop itself with no program running. So it's not video related.

@Apple: Hello there?

Best regards

Before updating to the new OS (Monterey), last night I got the screen flickering in my MacBook Pro M1. Some said updating to new OS will fix the issue. Updated. The problem still exists.

So far, I have tried:

-Display- Automatically adjust brightness-Disabled

-Accessibility- display- Color filter-Enabled

-Display-True tone- Disabled

-(as a few recommended) Accessibility-Display-Pointer(cursor)-changing to large and back to normal.

Tried everything. It just can’t seem to work.

This flickering started even before updating to new OS. Flickering is dramatic all over the screen. Has to be a software issue, right?

Thank you kindly for any other suggestions. Cheers!

Hi thedoctor47,

Thanks for coming to Apple Support Communities for help today with your screen flickering issue.

You mentioned this happening in Safari. Does it happen in every site you visit for videos? For example, does it happen in Netflix and in YouTube?

Does it happen if you play a video thats stored on your Mac?

Does it happen if you use the Apple TV app on your Mac?

Let us know further details.

Have a fantastic day!

Same here getting real bad flickering since upgrading to Monterrey mainly in games. Using 27inch 2020 iMac 64GB DDR4 Ram, AMD Radeon Pro 5700 XT 16GB Graphics Card. Is apple doing something about this?

Hi, my screen started to glitch on full screen mode while watching Netflix after updating to Monterey. Tried both Safari and Chrome.

Model: MacBook Pro Retina 15"

OS: Monterey 12.0.1

Processor: 2,2 GHz Quad-Core Intel Core i7

Graphics: Intel Iris Pro 1536 MB

I have a new MacBook and it is working perfectly. I think it has to do with and AMD graphics card since I know it was giving issues with Metal. AMD is bad but I don't know if it is the issue for sure. Apple I guess isn't even addressing the issue.

I have a MacBook Pro 13" (2015) and after upgrading to Monterey the screen is randomly flickering in almost every app I use. i tried several "screen flicker fixes" I found online and even re-installed Monterey. Nothing works. Any help out there?

Thanks

I get a black bar that flickers. It is inconsistent. The black bar does not stretch across the screen on my 2017 iMac 27"

its not really all that bad, but it happens in programs and it is random. Sometimes it happens in the same program while using it

and sometimes it doesn't. The black bar flickers so fast that I can't catch all the detail. I am also noticing it on my iPhone 12 the past few days. The black bar flicker is minimal though, but annoying. I can't exactly pin point all the programs it happens in, but I do notice it in adobe photoshop and maybe in Illustrator. I t is hard to pin point, I am also guessing it happens in videos online.

If you need more detail let me know.
