PS 2019 - Transparency display corruption?

[Mike_Jensen_TG]

From Photoshop's own tutorial image, I've noticed there is a transparency corruption issue.

iMac 27in, Late 2105

Retina Display 5K

MacOS High Sierra 10.13.6

Photoshop 20.0

This is how the image with several layers with transparency appears in PS 2019:

This is how the same image appears in PS CS6 (correct):

I'm not sure if there is a setting which is creating this issue, a bug, or...?

Hi Mike,

I believe those are artifacts which might be occurring due to a problem with the Graphic drivers, could you please check if you're using the most recent graphics drivers? If not, could you try updating the graphic card drivers from the manufacturer's website?

Also, could you please try deselecting "Use Graphics Processor" located in Photoshop's Preferences > Performance, then relaunch Photoshop and let us know if it helps?

Sahil,

Thanks for the quick response. iMacs afaik roll all their graphics drivers updates into their general OS updates. And I have the latest update pre-Mojave.

I tried deselecting "Use Graphics Processor" and restarting PS, but it didn't fix the corruption.
