High Sierra screen artifacts

Having exactly same issues on High Sierra. Especially on dark grey backgrounds - see attached photo below

All those lighter elements are artifacts that are like ghosting of things that were displayed earlier - like fb page or icons of the background visible on the right side.

You should actually see a smooth grey background - below is a screenshot of the same thing:

Few things:

- artifacts above are visible only on my iMac screen

- they are not visible on the 2nd monitor

- had to take a photo just like LuxViz as they are not visible on screenshots

- when they start to appear - it seems that my iMac is slowing down - especially when I jump from one desktop to another - it's just jerky animation

- I assume that all that suff have something to do with Metal 2 introduced by Apple in High Sierra - as you can read on the internet: "Metal 2 includes driver optimizations, and Apple claims that it brings up to a 10 times better draw call throughput. More debugging tools are now available, and the Mac Window Server has been migrated to Metal as well to enhance performance of the system-wide animations."

- 2nd monitor issues:

I do not have artifacts but have strange grey rectangles appearing on dark backgrounds. And I can take screenshots of those "rectangles". Sometimes they are flickering. See below screenshots of Spotify app on 2nd montior and on iMac:

EXTERNAL MONITOR:

iMac DISPLAY (THIS IS HOW IT SHOULD LOOK)

On top of that I am experiencing "locking" issues - I have to restart my iMac as only my mouse cursor is responsive and nothing else, including not responsive keyboard and screens are not refreshed at all. But this is a known issue to Apple and you can find more info about this elsewhere.

I hope Apple will solve this issue soon - seems that 10.13.1 update is even worse.

My iMac specs:

iMac 27" Late 2012

3.4 GHZ Intel Core i7

16 GB RAM

NVIDIA GeForce GTX 680MX 2GB

Same issue on my iMac (27-inch, Late 2013)

After the upgrade to High Sierra image retention is much more prevalent.

Image retention is absolutely normal, but now happens almost immediately, is much more pronounced and take much longer to dissipate. It's also a weird reddish colour for some reason.

I am also having the same issue on my late 2012 iMac 27".

It only started after I updated to High Sierra, screen was working perfectly before. The only way to get rid of the burn in is to run "Flurry" screensaver for a couple of hours, this removes the burn in temporarily.

Having to do this every lunch break and evening as I use the iMac all day for my job. Very frustrating!

Clearly there is a driver issue with some graphics cards. It outrageous that Apple is silent regarding this!

Have some very bad images to show but you can get the idea of the burn (this is quite mild, usually have a lot more browser window burn-ins).

Is this on your 2011 27" iMac? Some of those models had a defective GPU which gave out and was replaced on a recall that ended 4 years from the date of purchase. I had mine replaced just under the wire.

That looks like a graphics issue. Since that model iMac is considered vintage (except in California and Turkey) Apple will diagnose it free but can't do any repairs. I'd take it in to the nearest Apple Genius Bar for a free diagnostic test.

If you want it replaced you'll need to find an Authorized Apple Service Provider who'll have or can get parts and repair it. I've heard report of about $500 or so for the repair.

My 2011 iMac failed again about 6 weeks ago (graphics chip) and was laid to rest in a moving ceremony.

Shut down and restart is fundamental for sorting random anomalies.

You could try reinstalling the macOs on top of your existing macOS

or

you could wait for an update 10.13.1 and see if this address the issue.

> First I tried to install High Sierra again, I thought it might have bugged on the last install. Nope.
> Then I backed up everything manually to an external hard drive and installed High Sierra from the scratch like I would be selling my mac, meaning I would have to install all my apps, fonts, and so on again. Did not help.

> After that I googled a lot how to do "downgrade" to the older version which Apple seems to made hard if you don't have experience with terminal or don't know about formatting but when I Followed multiple tutorials I managed to it quite easily but took a long time.

I did this last night and I can't promise I remember all the steps right way but shortly this is what I did I downloaded old os, made a USB stick installer and wiped everything in my computer. Found some good instructions here:https://www.macworld.com/article/2981585/operating-systems/how-to-make-a-bootabl e-os-x-10-11-el-capitan-installer-drive.…

1. Backup everything

2. Double check you backed up

3. Download the el capitan from App Store

4. Format, rename and partition 8-16gb USB stick the proper way (link up there tells everything^)
5. Move the installer to the formatted stick
6. Restart the computer with special command, erase everything from the hard drive (the link I posted did not mention this part so when I Rebooted with command + r and used disk utility to erase my hard drive (it will pop up macOS recovery with this command: About macOS Recovery - Apple Support)

7. Rebooted again with command + option to Install El capitan from the stick (the stick wont show with command +r )

8. Hope, pray and sacrifice your soul then wait that the installation goes all the way to the end and for me this took ages, it looked really worrying once in a while with looong stops only white screen showing or text saying " about a second left" meaning 20-30 minutes but IT WORKED.

No screen problems, ghosting or "burns", no lagging, no pinwheel of death at the moment.

Same issue here, 2015 5K iMac. Used for a year with 10.12 Sierra without issue. Updated to 10.13.3 High Sierra last week and now images are retained within 5 minutes of being on screen (like desktop icons etc).

Funnily enough, using Windows 10 in boot camp with screen on and static images displayed for hours does not see any burn in/retention.

Same issue here. Late 2013 iMac that started to have image retention the day I upgraded to High Sierra. Tried the Nvidia webdriver (CUDA) but issue remains and it is actually rather problematic if you like myself work a lot with Photoshop or After Effects.

The artifacts or image retention starts to happen after a few minutes of usage.

How do we know or make sure that Apple is going to address this issue?

Also having the same issue...Before upgrading to High Sierra it appeared rarely, but after update started to appear quite often

macOS 10.3.2 (17C88)

iMac (27-inch, Late 2012)

3.4 GHz Intel Core i7

NVIDIA GeForce GTX 680MX 2 GB

I have the exact same issue with my mid-2012, 27" iMac. It's been occurring for about the past 6 months and I've tried to ignore it, but it's getting worse. I contacted support through Twitter and they had me do all the standards things that others have done (and that I've done on my own)...but nothing has been resolved. These seems like it may be more of a hardware degrading problem. It's extremely problematic for doing any photography work b/c of the constant artifacts and bleeding.

I seriously doubt Apple would provide replacements/fixes for ~6 year old machines without significant cost. The idea of having to buy a new machine is not something I'm hoping to do.

I wonder if Apple tests these upgrades? Any programmer would experience this problem that we all share in this blog. And it doesn't matter which program we are running, then quit. There remains a 1-3% ghost artifact of the last window on top of any current active program window. It makes watching video difficult and distracting. And a restart doesn't solve the situation. Sometimes it does. Most times, it doesn't. The iMac is supposed to be the most sophisticated computer in the world. Did the guy who vetted this before release have a death in the family?

The next time Mac offers a software upgrade.... I will wait until it's absolutely necessary before irreversibly upgrading.

Fool me once, shame on you. Fool me twice...

There is one method to reduce these effects. Tighten up your display sleep times to 10 minutes in Energy Saver and use a variable slide (animated) screen-saver pattern set to five minutes or just before your chosen display sleep time, in Desktop & Screen Saver. You should see a drastic improvement in this bug.

Wait for the next upgrade, but read the fine print first to discover whether it solved this particular problem. If not, don't update.

Good luck, Chris

So we should stop our work every ten minutes, let the screen saver run for 5, let the display turn off and then rinse and repeat? Seems like a total productivity killer. The problem most of us here seem to be having is severe image retention during normal, such as writing this reply. Unless I move the screen around every minute, I am going to have image retention linger. Does it go away eventually? Yes, but not after staying up on the screen for an annoying amount of time. For someone who is doing design work, it gets to be very difficult to accurately view what I am working on with these artifacts getting in the way.

Yeah, I also think that's not really any kind of solution if you're doing anything productive. The fact is that screen retention wasn't really big problem before upgrading to High Sierra. I already submitted bug report to apple. There are no any replies from them yet. But I think you should all also submit bug reports so they can notice it. This forum is not official place to submit bugs. The more people submit the bug in the official place the more likely they will do something and react.
