This conversation has been merged. Please reference the main conversation: Photoshop CC 2019: Artifacts on image while using uniform color with Color blending mode

The blend modes Darker Color, Lighter Color, Hue, Saturation, Color and Luminosity aren't working properly when using adjustment layers .

I have both CC 2018 and CC 2019 installed on my Windows 10 System and using any adjustment layer with blend modes works correctly in CC 2018 but not in CC 2019.

For example blending a red or cyan color adjustment layer in blend mode 'Color' produces a grey monochrome effect on the image below. Blending other color adjustment layers in 'Color' blend mode produces weird colours. 

I've also noticed that using other adjustment layers in blend modes Darker Color, Lighter Color, Hue, Saturation, Color and Luminosity produces weird effects as well.

I've followed some threads here in Photoshop Family and enabled Legacy Compositing and that has rectified the problem in CC 2019. Why though?

I don't understand the first thing about Photoshop's compositing engine and why CC 2019 is different so would appreciate it if someone could explain. 

What is the difference between the legacy and non-legacy compositing and will this issue be addressed?

My Graphics driver GeForce GTX 970 is up to date.
The issue is not present in CC 2018 which I still have installed.

Please try the following:

Preferences > Performance... and check "Legacy Composting" - Restart Photoshop. Does the blending work correctly?
