Mesh Instance - JPG texture rendering issue

Question

Hello,

I'm totally new on 3D, I'm trying to follow some tutorials to render a JPG image of the earth on a sphere. It's almost working but I have an issue.

This is what I've done:

1. Created a Mesh instance element under earth KinematicBody
2. Add a SphereMesh to the mesh node
3. Add a SpatialMaterial to the mesh node
4. Add Albedo Texture to the SpatialMaterial
5. Remove some flags to improve the rendering of the JPG over the mesh sphere (Minmaps and repeat)

When I arrive to step 5, on the editor I see the JPG perfeclty rendered without repeat and minmaps but when I play the scene the earth is badly rendered, on the editor the definition is really high but when I play the scene is awful:
<br/>

What is the issue here ? Is related to the Camera node ? some missing configuration on the Mesh or other node ?

Thanks

UPDATE

Godot Version:

OS version: macOS Mojave
Graphic Card: AMD Radeon R9 M290X

Comments

Which version of Godot are you using?
Which platform are you on?
Which graphics card?
Looks like a bug that could get reported.

Is it just 3.0 or 3.0.6?
