PS 2019 – Color Blend Mode Buggy

I just installed the new CC versions and opened the file I last worked on in Photoshop 2019. I was surprised to see a severe color shift on the paper in the center:

This is how the file looks when opened in Photoshop 2018:

The image of the paper has a color blend mode of a sand color, but appears greenish!

The background layer is just a solid rectangle. When color blend mode is chosen it becomes greenish and there is a stripe in the paper.

The file still is displayed correctly when opened in Photoshop 2018!

What can cause that issue? Bug?

Can you go to Preferences and check 'use legacy compositing' and try it again

Hi Lindy,

Adobe is now aware of the issue. In the past when a new major version was released there were often bugs that got fixed in a subsequent update. We can hope that'll happen soon this time around.

Just to circle in on possible variables, I updated the Quadro to 411.63, which is the latest "optimal drivers for enterprise" version. It was at 390-something.

Everything is still performing perfectly.

(And yay! - 30 bit works now! It didn't for so long that I thought it was broken by a Windows Update.)

For what it's worth, I have had to reselect the 30 bit mode in the nVidia control panel after every driver update. Even though it LOOKs like it's already set, as though it retained the settings from before, it really didn't.

Is it possible to drag a PSD file to this forum to post it? It would be good to have just a small one with which to reproduce the problem.

Sorry, Noel, can't do that. Have to use dropbox or something else.

As Mark mentioned, PS has a new compositing engine that crunches layer data and is suppose to be faster. It is a rewrite of the base code. There are still issues with it, but those will be worked out. Sometimes, just turning a layer's visibility off then on will correct the problem for that layer, but if you are having issues, it's best to use legacy compositing.

There are still issues with it

But under these circumstances the affected people may find its release without accompanying announcements* a bit irritating.

*: At least I found no mention of it in the »What’s new«-section.

I am absolutely unable to make anything break here. It all works smoothly, instantly and entirely as expected - with Legacy Compositing unchecked.

All these layers are in Color blend mode:

The card is NVidia Quadro P600. It hasn't been updated for a couple of months since there hasn't been any need (and I'm waiting for news on the 30-bit situation):

I just did a test. When I add a shaper layer on top of an image the color blend mode does not work. When I create a new layer and draw the rectangle as pixels color blend mode does work. When I draw a shape rectangle, set color blend mode it does not work, but as soon as I rasterize the shape layer the blend mode does work. It seems to be an issue with shape layers!

I have both CC 2018 and CC 2019 installed on my Windows 10 System and the adjustment with solid colour using the 'Color' blend mode works correctly in CC 2018 but not in CC 2019.

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

I've followed some threads here and have 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?

What is the difference between the legacy and non-legacy compositing?

A valid question and something Adobe has not offered a lot of information (or any) on … (Edit: or at least I failed to find that information so far.)

Do all the affected parties work on Windows, though?

The compositor crunches layer data for screen display, and there is a LOT of performance upside to upgrading it. The differences between Legacy on or off are too numerous to mention, but you are not losing out a bit if you find it necessary to use the Legacy option.

I'm having an issue in some blend modes where random squares are introduced (see red in image), and I had photoshop hang on me and get really slow in select and mask mode. Legacy mode seems to have fixed the blend mode issue, dont know about select and mask lagging though.

That last one looks like a video driver issue.

Don't have that issue in the latest 2018 photoshop, and as I mentioned, it went away with legacy compositing on. IDK if its helpful, but these are my computer specs:

Hi there, im having the exact same issue, when i use and adjustment layer with solid color and use with the layer blending mode "color" it becomes almost unsaturated dark purple, which didn't happened before the update. Below the example, it was supposed to be bright

red:

(i need this fixed asap, its affecting my work...)
