Broken: version: 2.83.0, branch: master, commit date: 2020-06-03 14:38, hash: 211b6c29f7
Worked: 2.82a

Short description of error
If render with my GPU, strange lines appears, even in the 3d viewport with viewport shading. Just formatted my windows and installed tha latest GPU driver (20.5.1) version with Radeon Software. Downloaded experimental build of blender (blender-2.83.0-82e3bd4bbb82-windows64) and the bug persists.

The lines are shown in the defult new file with the cube too. No need to open my attached file to reproduce it.

Render in 2.83 LTS

Render in 2.82a (portable downloaded)

blend file for example (tested in many files) planta_baixa.blend

Scrren with configurations and bug in view shading

Exact steps for others to reproduce the error
Edit > Preferences > System > Cycle Render Devices with OpenCL: GPU Only or GPU + CPU Selected.
Render properties menu > Render engine: Cycles; Feature set: Supported; Device: GPU Compute.

[Based on the default startup or an attached .blend file (as simple as possible)]
