Photoshop artifacts on background

[creativedharma]

Working in photoshop today, 8/23/21, and this is what keeps coming up. (see attached)

Does anyone know why the artifacts keep coming up and how to get rid of them?

I"m working on CC 2021 5.5... on a mac book pro 16"

All the apps are up-to-date.

I tried getting rid of the preferences. No help.

This looks like a graphics card issue - can you send a screenshot of your performance/preferences window and include the advanced settings?

[creativedharma]

Thanks for replying. This is what I did.

I went into the performance preferences and unchecked "use graphics processor" and the artifacts went away. Now I'm trying to figure out if it's the graphics card.

First, try disabling GPU in the preferences (Preformance tab). Any better?
If not, recalibrate and build a new ICC display profile, the old one might be corrupted.
If you are using software/hardware for this task, be sure the software is set to build a matrix not LUT profile, Version 2 not Version 4 profile.
Some have reported color issues with displays that have an HDR option. Open Display Settings and toggle off the "Use HDR" switch if such an option exists.
If turning OFF GPU works, it's a GPU bug and you need to contact the manufacturer or find out if there's an updated driver for it.

Thanks for replying.

I did turn off the GPU and the artifacts disappeared.

See attached. That's why I turned off.

I'm having the same issues. It only seems to occur when I am working in RGB, if I'm working in CMYK no problems.

Tried uninstalling and reinstalling and unticking Open CL, no joy.

Working on:

iMac (Retina 5K, 27-inch, 2020)

3.1 GHz 6-Core Intel Core i5

16 GB 2667 MHz DDR4

AMD Radeon Pro 5300 4 GB

Hi,

I went into the preferences in Photoshop --> performance --> unclicked use graphics processor.

That seemed to work. I have no idea why after all this time it happened.

I think next up is the Genius Bar.

Try enabling this option in preferences and restarting Photoshop to see if it helps

[Nicko123]

Bingo,

Cheers Ged.

Got the same issue and while this does fix the bug, it makes zooming/panning unusably slow.

Thanks for the reply, but I'm afraid that (disabling 30bit display) hasn't worked for me.

Take a look at this thread, alas that forum is now read only, but see the last reply from Mark Dahm

OK thanks, nothing to do but wait, or maybe (possibly) updating MacOS will sort it.

Thanks for replying. That's wasnt checked.

Not sure if useful but updating to BigSur has just fixed this bug for me.

[creativedharma]

Thanks for the info. I believe I have an update waiting.
