Liquify Tool Black pixels after MOJAVE OS

[LinkNYC]

Just updated my Mac to Mojave today.

Liquify is creating black pixels when used.

I have tried to optimize performance but I still get the same error.

I have a super fast machine, so is not a RAM error. Liquify was working normally before Mojave OS.

In the image below, I have slightly adjusted the smile of the subject.

Hi

I use Windows here so cannot test for you. However, if you have a repeatable bug it is worth raisng at the link below where it will be seen by Adobe staff (this forum is answered mainly by volunteer users). Please give details of your system and Photoshop version.

Very often, it takes an application some time to catch up with OS releases and vice versa. It's possible that Mojave has a bug with your video card (yes, that even happens with native Mac cards). It's possible that Photoshop needs a dot release to fix the issue on the Adobe end. Mojave is so new, we're going to see quite a few bugs between the OS and many of our apps, until things get smoothed out (it was released today, so the full volume of issues hasn't even arisen for most people yet). I strongly recommend following davescm​'s suggestion of posting to the Customer Community, and hopefully enough people will have a similar problem so Adobe gets right on it. Or, wait for the MacOS's .1 release, which often fixes issues like this that come up, as well.

YESSSSS!!!

So it's not just me. On Mac Pro (2013), 32GB Ram, 12 VRAM.

Changed all the GPU settings in Photoshop to no avail. Everything else seems to function properly.

Note they're little "dots" if you are working with full rez files. However if you're working with smaller JPG files they become little funky artifacts.

Me too bro. 2013 Max Pro 32gb RAM. AMD 500 Fire Pro.

That is interesting. I'm running Mojave on a mid-2012 MBP that uses a 1536 MB Intel HD 4000 card and 16 GB laptop memory. I don't see this on CC 2018 19.1.6 playing with the same image you provided.

What might be worth trying is installing CC 2017 or even 2014 to see if it has the same problem.

Usually older versions stress the graphics less.

If you have an "energy saving" onboard Intel card on your system, you can see if switching to that helps.

Hi!

Here is some information that might be helpful in regards to Mojave and Photoshop:

Hope this helps!

OMG! Thank you! This was causing me all kinds of problems and this workaround is so quick and easy!

[jamyks]

The same problem.

So already this is one Mojave problem not covered in the official "known issues" document. More will come.

It cannot be stressed enough: Don't upgrade to a new operating system release until the initial problems have been identified and resolved. Wait until the dust settles and you know what you're getting into.

A new major CC release is coming shortly, tested and ready for Mojave. I'd still wait a while and see how it plays out.

[Thijs Louis]

I had the same problem and found a workaround for now...

If you disable your graphics processor (photoshop prefereces > Performance > uncheck "use graphics Processor"), the pixel problem disappears. It's not the best solution, but it will work for now...

Hopefully Adobe will address this problem in an update... Fingers crossed!

In the post immediately preceding yours, I said, "A new major CC release is coming shortly, tested and ready for Mojave".

What broke this wasn't Photoshop CC2018, but a brand new operating system from Apple, changing the old rules, and which users didn't have to install on day one. They could have just waited until the new, Mojave-ready Photoshop CC release, which is expected any day now.

[Thijs Louis]

I meant: Hopefully someone will address this this issue, didn't mean to point any fingers...

For me the little dots are more an annoyance and EASILY fixed. And quite frankly it's the ONLY quirk I've found since the OS update. ALL of my plug-ins (Nik, Topaz, Portrait Professional, Portraiture, etc), Lightroom, Capture One Pro, and other photo apps all seem to be working fine.

Whether it be on a Mac or PC, with each major OS upgrade there are going to be random issues that crop up with any application installed on the platform. No one HAS to install an update day one, but they do have the option to make that choice (and accept the consequences). Actually when you say there is a MAJOR Photoshop update coming soon to "fix" the problem, although "tested" with Mojave, we make assumption that no other issues are going to pop up due to the update. Regardless of the size of the testing group for the update, you can never rule out those nasty little buggers that WILL pop up when you release it to the masses and all the different variations of Macs out there. 

Seriously, you KNOW we can't wait to put new stuff on our machines, break them, and then all meet here again to go WTF

How are the little dots easily fixed?

[PPhotography808]

I'm sorry...I should have said easily fixed with healing brush. I've never seen more than maybe a handful of dots at any giving time and they're usually around the area I just finished working on. So, a dab here and a dab there...seriously less than 30 seconds of work. Hence, "Easily fixed". ALSO I'm talking about full rez images. As I stated in my first post, they're not "dots" in cropped jpegs...they are all sorts of lil geometric monsters.

Instead of disabling the GPU in the photoshop preferences, try just using Liquify without GPU acceleration.

Do this by holding down the Option key while clicking on Filter>Liquify

[AizatSelamat]

Hi Jeff!

clicking on option while opening the liquify tool works! No more F$^#ing annoying artefacts. Heck Yeah!

Im on the Retina 5k, 27inch iMac running on macOS Mojave. so whoever got this problem, just try this solution before they fix the damn bug – and they should do it ASAP! because it's a lil laggy to liquify BUT it gets the jobs' done for now.

[barubin88]

This doesnt work for me.

[Jeff Arola · Accepted solution]

Apple has just released the 10.14.1 Mojave update so install that and see if the Liquify issue is solved.

[barubin88]

Doubt it it’s an adobe problem

One or two posters already confirmed it had been fixed in the beta of 10.14.1.

[AizatSelamat]

[Jeff Arola]

macOS 10.14.2 is a beta so stick with the official 10.14.1 update.
