Created attachment 188634 [details] At 80% opaccity the colour of the outer stroke has completely overridden the inner stroke even through they don't overlap SUMMARY Changing the opacity of a stroke layer style for a polygon that is part of a group causes strange behavior where the stroke becomes the wrong color STEPS TO REPRODUCE 1. Create a Group layer 2. Create a Vector layer that is a child of the Group layer 3. Draw a polygon object on the vector layer, with fill set to foreground colour and no outline. 4. Right click on the vector layer, click Layer Styles, and add a Stroke that is coloured red, position Inside, Blend Mode Normal, Opacity 100%. Set the size to something large so that the stroke takes up a lot of the polygon (this just makes the bug more clear) 5. Right click on the group layer, click Layer Styles, and add a Stroke that is coloured yellow. Position Center. Blend Mode Normal. Opacity 100% 6. Observe that you now have a polygon with a red stroke surrounded by a yellow stroke which is expected. 7. Right click on the vector layer and click Layer style again to bring up the stroke properties. 8. Change the vector layer's stroke's opacity to 80% 9. Observe that the vector stroke changes entirely from red to yellow, completely overridden by the colour of the group stroke even where they don't overlap. OBSERVED RESULT When the vector stroke has an opacity lower than 100%, its colour gets overridden by the colour of the group stroke even where the two strokes don't overlap. EXPECTED RESULT The strokes should only effect each other's colour where they overlap and based on blend mode and opacity settings. SOFTWARE/OS VERSIONS Windows: Windows 10
