Hi everyone. I found that when choosing group blending mode as linear dodge, it would act in a differently from simply apply a linear dodge layer. An example:RackMultipart2016030396746zrsd-c38079b8-fb79-42cc-9d70-ce640bb2ea7f-59737878.png RackMultipart2016030331194bqoq-667f0203-9ccd-44e5-87af-38b5792eb4b1-401874920.pngUpper one the adjust layer, lower one the 'adjust group'. (in case these helps: Layer 1 consists of deep blue& white, the two layers are white rectangles blurred using Gaussian blur.)The group only contains one layer in normal mode which has identical pixels as the adjust layer does.Same thing happens for color dodge mode, but not for lighten, screen and lighter color. Seems blending type related. Searched for blending methods and group blending mode, but came to that in this case they should work in the exactly same way... Did I missed or misunderstood anything? This is a quite interesting feature but I'm curious about the mechanism.Thanks in advance.
It's easy to replicate the issue in photoshop 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.

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.
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.
