I have a "part A" that is transparent, so i can see the "parts B" behind it. When I am moving the "parts B" that are behind the transparent "part A", i lose the transparency in "part A". The transparency is only lost when i am moving the part, the second i let go of it I get the transparency back. Left image is when I am not moving the cone shaped "part B", and right side is when I am moving it.
I dont remember this ever happening before. SW 2017 SP3.0. Thanks for the input.
