System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce MX130/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 442.50

Blender Version
Broken: version: 2.83 (sub 6), branch: master, commit date: 2020-03-06 22:46, hash: blender/blender@dcdcc23488
Worked: (optional)

Short description of error
The Checker Texture would interlace when having Object coordinate vector mapping in Eevee

Exact steps for others to reproduce the error
Based on the attached .blend file, which is a plane with a default Principled BSDF, with Checker Texture hooked to the "Object" texture coordinate.

You can see the Checker Texture is interlacing.
Change your viewing angle, the interlacing is also changing with your view.
Go to Rendered View, change the render engine to Cycles, you can see it is doing fine in Cycles.
This isn't noted in the manual.

Thank you for the report. This is a known limitation that is documented in the manual for the white noise texture node, but not the checker texture node. I will update the manual.

One fix is to add an arbitrary small offset.

Thank you for the report. This is a known limitation that is documented in the manual for the [white noise texture node](https://docs.blender.org/manual/en/dev/render/shader_nodes/textures/white_noise.html#notes), but not the checker texture node. I will update the manual.

Evan Wilson changed title from ~~Checker Texture with Object Coordinate Strangely Interlacing in Eevee~~ to Checker Texture precision limitation not noted in the manual
