Transparency / Blending Modes stuck
I experience regularly that Transparency and Blending modes doe not relfect what the controls / parameters say.
An example in the screenshots: the Triangles with the green Gradient are Blending Mode Normal / 100% (have been transparent before, but switched back). On white everything seems normal, but as soon as the blue background is switched on, we see that the blending mode is not Normal. The selection is not part of a Group.
