Texture of a large mesh shows artifacts when zoomed in
How to reproduce:
1. Open the user's attached project("Urp Bug.zip")
2. Load "Sample Scene"
3. Look at the plane in Scene View
Expected results: The texture is fine
Actual results: The texture has artifacts
Reproducible with: 2018.4.29f1, 2019.4.15f1, 2020.1.15f1, 2020.2.0b13, 2021.1.0a7
Notes:
- Reproduces with all graphics API
- Reproduces with the legacy renderer and URP (7.5.1 - 10.2.0)
- Artifacts don't show up everywhere
- Doesn't reproduce on all computers
- Such a large Mesh can be obtained using ProBuilder

Latest issues
- ResolveUsePasses now extracts passes from all subshaders including fallbacks, in contrast to documented behaviour
- [UIBuilder] Changes aren't detected on types implementing IList
- [HDRP] Text is rendered with artefacts when using STP and resolution scale is set a float value
- [Settings Search] Search results not always matching search term correctly
- Crash on memcpy when opening a project that loads TSS files
Resolution Note:
Based on the repro project setup and the video I've concluded that is by design:
By zooming in so far on such a large plane/triangle, the precision limits of the GPU's interpolators/texture samplers is reached.
Adding a few more subdivisions to the plane should already alleviate this effect.
