System Information
Operating system: Windows-10-10.0.17763-SP0 64 Bits
Graphics card: GeForce GTX 1050 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 432.00

Blender Version
Broken: version: 2.82 (sub 6), branch: master, commit date: 2020-01-24 17:48, hash: fc1f5bded4

Short description of error
Rendering scene with CPU and GPU turned on, don't render all tiles correctly.

Exact steps for others to reproduce the error

Create any simple scene with lightning
In preferences have cycles render device - CUDA with both CPU and GPU checked
Render it on GPU Compute or CPU (it makes no difference)
It renders image with some not fully rendered tiles.

Rendering works absolutely fine if only one (GPU or CPU) is checked.

Thanks! :>

I will have few more requests:
First, make sure your GPU drivers are up to date and check if this problem exists in latest Blender version https://builder.blender.org/download/

If there still problem, Upload simplest .blend file so we can reproduce the problem.
Can you also add image of correct render to compare with buggy one? I kinda see problem in last image, but not sure how those blue cylinders should look, and what the problem is.
