This is one, in my opinion, visual bug which have persisted for many version updates and no one seems to mention it because it has become "part of everyday KSP". I'm talking about the transparency issues in the VAB/SPH. I'll show you a few screenshots of what I mean.

Here is a screenshot of a FL-T800 fuel tank about to be placed [FL-T800.png]. As you can see the tank itself is transparent to make it easy to place on the underlying surface. Easy, nothing strange here.

Here is a screenshot of the big orange tank about to be placed [Orange Rockomax.png]. Huh? What a minute, doesn't something seem off here? Why can I not see the tanks and crewpod behind the transparent tank? Why is the big engine the only thing that is visible?

Here is a screenshot of a SRB about to be placed [SRB.png]. Okay, now everything including the engine is not visible. What gives?

This transparency problem makes it especially difficult to place anything on top of decouplers [Kerbodyne1.png] since the decouplers (and more) disappear [Kerbodyne2.png].

Sorry about the formatting, here is a link to my original post on reddit which is easier to understand:
