Created attachment 188213 [details] Compare 3D-cube with 2D-square Open attached document. It has a 3D-cube and 2D-square which use the same graphic style. The style uses a gradient with 60% border (UI "Transition start"). It has three gradient stops: offset 0 color #0033ff offset 0 color #ffff00 offset 1 color #ffff00 The 2D-square renders it correctly, but the 3D-cube has a wrong color in the area of the border.
It effects extruded custom shapes too. That is a problem, because extruding a custom shape (and setting depth 0) is a trick to get a fill rotated with the shape.
