This is what x-ray mode is for. What setting did I bork to make this happen in solid mode? How do I fix it?
But whatās your problem an what exactly do you need? no wireframes visible?, no x-ray?
Both x-ray and wireframe are unchecked.
Yeah, I just want it to be solid, like in 2.79. If I want to see through it, Iāll enable x-ray or wire frame.
batter share the Blend then, for more investigations
OK, I just stuck a couple cubes overlapping each other so you can see it.
Was too big to zip up and drop here, so itās on Google Drive.
Itās some setting somewhere Iām sure. I opened up a brand new file to make these cubes and didnāt have the issue. It wasnāt until I dropped the cube into the project I was working on that the transparency came back.
I saved my project with another name so I could delete all the assets, and just have the cube, the idea being to keep the file size as small as necessary. So this would be the same just without all the assets.
(I suppose I could just copy/paste all my assets to a new file, but what would I learn? 
)
Your .blend looks the same here. I think this is considered a feature, that edges which are behind other objects (or parts of the same object here) are made visible in cases such as when penetrating a ground plane. With this feature you can see through the ground plane and see the bottom of the object so itās easier to position relative to the plane because you can now see āhow much of the iceberg is under waterā as it were.
I know I recently saw a demo of this ānew featureā but Iām unable to find it offhand (looked at release notes and a couple other places.
Iām not aware of any way to turn this off at the moment (which doesnāt mean there isnāt some way I just donāt know of). Itās not an overlay or any other specific thing that I can find.
Copy the cube, and paste it in a fresh, brand spanking new .blend file and it wonāt look like that. (At least it didnāt on my end) It looked how you would expect it to look.
And I do remember the ground plane feature too, but I donāt remember much about it. Itās not something that was going to improve my quality of life, so I saved that limited brain space for more important things, like new hotkeys.
So Iām still having this problem, not sure if bug or feature, but itās really distracting when I donāt want x-ray to have a little x-ray anyway.
x-ray off;
x-ray on;
As you can see itās not full on x-ray, just a little bit x-ray.
Have you udated to the latest build? That was driving me nuts as well, but Itās fixed now.
Have you updated your GPU driver? Iām not experiencing it my end.
Yeah, just updated it a few days ago.
Weird. This is how it looks my end. Not much good to you, I know, but just so you can see itās not a āfeatureā but either a bug or some setting youāve enabled by mistake. Are you saying it doesnāt happen on a default scene, only the object in question?
It only seems to happen once I get a pretty good size file going. And itās happened more than once, which means I would have had to accidentally changed the same setting at least twice.
So if I start a new scene like you did there, itāll look the same, but if I created those same objects in my current working file, it would have that almost-x-ray look to it.
Current āmatureā file;
Copy/pasted to a fresh blend file.
Definitely a bug then. Iāll test it on a larger scene. Or are you only getting it in long-running scenes, or scenes youāve been progressively saving over a long period of time?
I would call it a scene Iāve saved many times over a long period of time. Iām using the outlier and collections to organize. So I have dozens of objects filed away in this scene, and Iāve been working on it for about a week or so.
Also, Iām just creating objects for a game, so itās a lot of the same sorts of things over and over again. No lighting, no backgrounds, not even materials beyond some basic colors to help me visualize the objects different parts that will be dealt with by the game engine.
Maybe you could just save all the objects in separate files and copy/paste as needed between files? This sounds like garbage collection in a long-running file. Something might have corrupted the file and hasnāt been flushed. This used to happen in Max, a few years back, due to garbage collection in the undo buffer.
That gave me a thought. I copy/pasted EVERYTHING into a new file, and the problem went away. However, my collections arenāt organized. I wonder if there is a way to copy/paste everything and maintain the collections too?
(Currently I have 57 objects)
