Description

System Information
Operating system: Ubuntu 18.10
Graphics card: NVidia GeForce GTX 680

Blender Version
Broken: After e5a1a9288c66ce218a03abf7666336a39ba03b8f ("Fix T60320: Cycles OpenCL denoising filter errors on some drivers")
Worked: Before e5a1a9288c66ce218a03abf7666336a39ba03b8f

Short description of error


Every tile rendered by GPU is black after denoising. Tiles rendered by CPU remain visible after denoising.

Exact steps for others to reproduce the error
Without denoising, everything is OK. If denoising is enabled, every tile rendered by GPU turns black after denoising. Even default cube scene is affected.

I have a similar problem with denoising.
If rendering with the cpu denoising happens.
If rendering with the gpu denoising doesn´t happen.
If rendering in mixed mode (GPU+CPU) only the tiles rendered by the cpu get denoised.

Here is as screenshot of the GPU+CPU rendering.

And the used blender scene.
