Mesh becomes transparent with UVs but is opaque without

[davidSFL]

Hi everyon.

When i open the uv editor either with a mesh selected when selecting it after the UV editor opened, the mesh becomes half transparent. Strange enough tho, this only happens on certain meshes, not all of them. I thought it might have something to do with a corrupt mesh, but cleanup shows no result and also i could'nt find any bad parts myself.

- The mesh has auto uvs, but it also happens with planar, spherical etc

- There is no texture assigned to the model (i know this can cause transparency)

- Standard lambert1 is assigned to the mesh

- Assigning different materials wont change transparency

- When i delete the uvs of this mesh it becomes opaque

- Once i auto uv it again, it becomes transparent once more.
- This mesh is part of a larger model, but its the only mesh this happens with.

- I've had this happen in multiple scenes with multiple modeles
- No wierd connections in the Node Editor or Hypergraph

Specs:
Windows 10 - Latest
i9-9900k
64GB Ram
RTX 3090
M.2 Ssd

Maya:
2020 - But happened with 2018 aswell

A quick google search yields no result, so this might actually be an issue specific to my end.
Any ideas anyone? Its not unuseable or anything, its just annoying and i cant figure it out

Hi!

Thanks for the file.

Please try the following:

1. Select the object

2. In Modeling menu:

Mesh Display -> Color Set Editor

3. Delete both color sets.
