Blender Version
Broken: 2.80.75, 76dfbee423, master, 2010-07-25

Short description of error
The UV map of the default cube are aligned in a way that some vertices make contact with each other in UV space but don't actually make contact with each other in 3D space. Cubes added manually are not affected.

Default Cube
Manually added Cube

To fix this the default startup.blend file would have to be updated. All other meshes, that can be added manually, do have properly arranged UVs by default. As a side note the "Quad Sphere" in the sculpting startup.blend does not have UVs, and is to my knowledge the only way to end up with a mesh without UVs.

Exact steps for others to reproduce the error

Create an Image
Create a Material
Set Base Color as Image Texture with image
Set Cube material to Material
Paint edges in Vertex Painting

There was another report about the default cube needing an update but alas, my search function literally does not work.

Hey, my search bar works again :) Related bug I was mentioning: #51332

That bug was filed in 2017.

Yeah, but I checked yesterday and the bug still seemed present. Although I doubt it's a very important bug, I just wanted to mention it, since it's a shame to have a partially fixed default cube :P. I just wish my searchbar worked initially so I could've mentioned it in time.

I also wonder though, and this question is relevant to both bugs, why is the code for creating the default cube not the same as other cubes? That seems like it shouldn't be that way, but I know very little about C code.

Looks like the geometry is inverted. Scaling the mesh of one cube in edit mode by -1 allows shape keys to work between the default cube and a newly added cube.
