Version 2.80 rc3 (Linux 54)

GP_proportional_edit_bug.blend

How to reproduce:

Open attached file, remain in edit mode.
Note the proportional edit settings and selected stroke vertices.

Move around the whole blue stroke, along with one vertex at the tip of the black stroke.

Observe how the black stroke is affected by the selected vertices of the blue stroke, even though the two strokes are not connected and are on different layers. This is not the expected behavior of the "Connected Only" setting. The strokes should only be affected by their own vertices, but as long as any vertex of either stroke is selected, they will affect each other as though the "Connected Only" setting is ignored!

I can reproduce bug in master d2063f7b

Fortunately, it looks to be limited to Grease Pencil object.

@lichtwerk I have been looking at the code and I'm not sure we can fix this, or at least I don't know how, because I don't know the transformation general code.

Actually, the transformation code is adding all points of any selected stroke (this is required because during transformation the user can increase radius size and include more points)... when the transformation is executed, the code check any surrounding point of any selected stroke to apply the transformation.... the problem is we have only the point, but not the layer or any other information.

Could you take a look at createTransGPencil funtion and the corresponding transformation code, maybe you know how fix this or maybe it's a limitation? In meshes the things are different because you have only one mesh data, so you can edit or not, but you haven't layers or things like that.

@lichtwerk I think we can set this a know issue.
