Today I've faced some kind of strange behaviour from blender 2.8.
I was working in Viewport Shading mode with x-ray off and geometry>wireframe off. Probably I had activated something because now after clicking on a green triangle in the scene collection window my wireframe completely disappears. The worst is that this behaviour persists absolutely everywhere. In whichever model I open that green triangle now removes wireframe and ever after restarting.
How to turn it off?!
That is original plane 1 with Object property> Viewport display > Wireframe unchecked however it exists.
