So different of Linear dodge between old and new versions

[fooxx]

This is the result in PS2014(both linear dodge & color dodge used)

And the result of same PSD in PS2018(in fact, 2015-2019 are all the same problem), so different, anybody noticed this issue?

I used to mention this issue, but seems no one regards what I said.

Is there anyone with the same problem as me?

Here is the TEST PSD.

The problem may be that non-chinese reading people may have a problem trying to download your file, even with the "aid" of online translation tools.

It's been brought up before

Photoshop: Group linear dodge may acts different from the layer linear dodge | Photoshop Family Cust...

i do know from first hand experience there is still a problem with group blend modes even in 20.0.5

[Jeff Arola]

It's easy to replicate the issue 20.0.5

1. Make a new document in sRGB, fill with 50% grey.

On the grey layer use a soft brush set to white and Linear Dodge (Add) in the tool options bar

2. Make a new layer, paint on that layer with the same white brush and then change the layer blend mode to Linear Dodge (Add)

and uncheck Transparency Shapes Layer in the Layer Style Blending Options.

3. Make a new layer, put the layer in a Group, paint with the white brush on the layer in the group. Then change the Group Blending Mode to Linear Dodge (Add). Now here's the problem that even if you uncheck Transparency Shapes Layer for the Group it still doesn't match the other two, assuming the other two is how it's supposed to look.

You can fix the group by filling layer 2 in the group with Black in the Behind blend mode, but for some other blend modes the fix is not so easy or it might not work on a particular document for whatever reason.

After further investigation it actually looks like the bug has to do with the Fill Opacity on Groups.

If you check Transparency Shapes Layer and reduce the Fill Opacity to 99 then it looks like the other two layers.

Thanks for your explanations, they are quite professional and detailed, and I think, unchecking "Transparency Shapes Layer" option maybe the best way for present version.

I never used "Transparency Shapes Layer" before, and seems need to use it from now on, it's a bit complex than before.

After further test, seems still the "Group+Transparency Shapes Layer" is handy operation, just like using Group in 2014, because "layer+Transparency Shapes Layer" can't apply layer style correctly.

Jeff, did you report it to the Photoshop team, either on feedback, or via other channels?
