{F6898864}System Information
Operating system: Linux-5.0.4-arch1-1-ARCH-x86_64-with-arch 64 Bits
Graphics card: GeForce GTX 1080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 418.56

Blender Version
Broken: version: 2.80 (sub 52), branch: master, commit date: 2019-03-29 00:43, hash: 99d4321fef
Worked: (optional)

Short description of error
View Layers yield different render results when using either F12 or using the Render Buttons on each Render Layer Node (Compositor). The result should be the same. I have only seen this occur with Grease Pencil for now.
I used factory settings to test.

Exact steps for others to reproduce the error
See attached .blend file:

Press F12 and see the result
Press RENDER on each Render Layer Node and compare.

@brecht I remember we had a similar problem when render in some situations with cycles. It looks the image of Cycles is not available when try to render the grease pencil or something like that, and the grease pencil is canceled. Maybe is a clue for you, but I tested that running in debug inside VS2017 always worked (maybe some thread priority topic).

If you render in Eevee works perfect, but when you render with F12 in Cycles (I set to new window render), the mask image is not created.

PS: Try to render, for example frame 83, to get a full image on mask layer.

@MichaelHermann Could you try using Eevee render?

@antoniov Seems to work as expected with Eevee. No issues.

Edit: I just tried Cycles again only GPU and only CPU with one thread. -> Same problem. (In case this helps)

Edit: It's really weird, now all it's working fine when press F12.

@brecht I'm not sure what is going on here. Could you take a look?

Try with my simplified test file.

@antoniov I am not able to reproduce this issue anymore. Are you?

Antonio Vazquez commented

@Jeroen-Bakker I cannot reproduce the issue anymore with last compilation, so I think we can close the report.

I am still seeing the same results in Cycles. In my file, as well as in your testfile, @antoniov
I tried with the build from last night.

@MichaelHermann You are right, I tested by error in Eevee. In Cycles fails.

Ok I understand. the issue is that the GP layer on the mask is not rendered during final rendering. When rendering individual layers it is.
Might be a pipeline issue. will look into it in more detail.

Eevee seems to be the only one that composites the results correctly during rendering.

When workbench is selected the main scene GP_Eye will already have the Mask composited during final rendering. while rendering individually this is not the case.
It might be this is the result that workbench does not support output layers.

Seems to be an issue in the draw manager. It assumed that the first renderlayer was the one that GP needed to draw on. When having multiple renderlayers this is different, this was neglected by the draw manager.
