[bug] Texturing decimated mesh bug

[bgpantojar]

Describe the problem
I am decimating the mesh using MeshDecimate node after MeshFiltering Node. After decimating the mesh, I use Texturing node coming out of the MeshDecimate. The textured mesh increases the number of triangles considerably. In my test I have the following approx numbers.

Mesh after Filtering: 400k triangles
Textured mesh just with MeshFiltering node: 400k triangles
Mesh after decimate: 38k triangles
Textured mesh using as input the decimated mesh: 337k triangles

When opening the textured mesh it looks like the decimated one, but it has the increased number of triangles.

Is this a bug? or it is an expected behaviour?

Best,
Bryan

Hello again...

This was tested with the last version of meshroom. Defenitely it is a bug as I did exactly the same with the 2021.1.0 version and the textured mesh of the decimated one kept aprox the same number of triangles.

Best,
Bryan

Does the textured mesh actually have that number of triangles or is it just an issue with the display?

I opened the file with a text reader and it does have that number. Same thing opening it with meshlab.
