Photoshop: "Use Graphics Processor" Not Working Properly With Latest MacOS

I have been in the support calls with both Adobe and Apple. I have the latest iMac Pro and I am trying to use "Custom shapes" inside of Photoshop with heavier custom shapes like rocks, and it simply doesn't work smoothly with the graphics card. If I shut off "Use Graphics Processor" the custom shapes work fine, but I want to have it turned on. Sometimes it even freezes Photoshop because it doesn't paint the custom shapes and just loads.

My Macbook Pro Retina Mid 2015 15" used to work perfectly with Custom Shapes, but once I have the latest High Sierra, it stopped working properly as well. 

The graphics card that seem to have this bug are the new Radeon Pro Vega 64 16GB, and the GeForce GT 750M. The iMac Pro should be a concern for Adobe as it's the latest and most powerful iMac out there.

It is very frustrating and I can't do my work properly.

Is this what you are seeing? https://feedback.photoshop.com/photoshop_family/topics/retina-screen-resolution-slows-down-pathing-i... (Sounds like the same issue which is being investigated)

It really does look like the same issue! This never occured when I was using my older Macbook Pro, but it has started doing that now since a few months back.

But the problem remains.

Is it something Adobe are working on fixing? :/

Thanks for your comment!

I am using "Low res" option now and it works a little bit. It's still quite laggy and not at all as nice as I used to have it a few years ago with earlier versions of Photoshop and MacOS.

Is Adobe looking into this at all with the retina and photoshop and mac or am I doomed as a illustrator to use a brand new $10k iMac Pro and not be able to use it properly? :(

Thank you for your assistance, Jeffrey.

Best,
