Question

Liquify creating black blocks

Since the last update, I've been experiencing some issues with the LIquify tool.  After using the Twirl Clockwise tool quite heavily under liquify to get the result that I'm looking for, I click OK, but the result that it outputs contains square black blocks.

As an example, the image below is how it appears while still in the LIquify tool, and then after the filter has been applied.  I've tried disabling my graphics processor with no difference.

In Liquify tool

After applying liquify

Has anyone come across this issue before and is able to assist please?

Thanks,

Steven

I do Photography every day- THis bug first came up with the Mojave update- It went away with the first patch and has been there for the last two patches. Fixing these black dots are seriously time consuming and look terrible to clients and managers as they work beside me to achieve the desired look.

Before Liquify:

After Liquify:

Here is my System:

Everything is up to date... GPU and everything...

Fix this please - its a major work flow jam. Dont deke it- Fix it!

Its a known bug, I think disabling graphics acceleration fixes it for now.

That is not a fix--- its a major bottleneck in my work flow -- the process takes infinitely longer without the acceleration... THIS IS NOT A FIX--- so people here have to address it as a super lame ineffective, inefficient work around--- NOT A FIX..

    check out the memory (Ram) do you have enough?

    Depending on the size of the file the liquify might not work correctly if you do not have enough memory.

    And like it mentioned on the other answer : check the graphics card.

    Make sure you have the latest GPU driver's:

    If the problem persists, a test and temporary workaround is to uncheck "Use Graphics Processor" under Edit>Preferences>Performance, then restart Photoshop. If that works, enable the GPU again and try "Basic" drawing mode under the same directory and "Advanced Settings."

    Thanks very much for the suggestions.  I've tried updated to the latest AMD drivers, rebooting, and resized the image down (it was originally 12000 x 4000, and I dropped it down to 6000 x 2000).  The image is 93 meg and I'm running on 16GB of RAM with 43% utilised and 7% CPU utilisation.

    I've tried it with Smart filters on and off, and tried all 3 of the Graphics processor settings as well as unchecking and checking the additional options. However, When switching off the GPU usage, the image shows up as having transparent spaces in the liquify tool, which I know can appear when you overdo the twirl tool. 

    It seems the issue is with the liquify mesh itself.  I've tried loading the mesh onto other images and it's giving the same results with the black blocks on these as well.

    If anyone has any ideas of other things I may be able to try, it would be greatly appreciated.

    Thanks

    Steven
