Apologies if not a bug; couldn't figure it out:
Operating system: Linux-4.18.0-25-generic-x86_64-with-debian-buster-sid 64 Bits

Short description of error
With a black (0,0,0) world, rendering in workbench generates a not-quite-black background. (I'm told it was the same in 2.80, but haven't checked myself.)
Exact steps for others to reproduce the error
- start with a blank config directory
- go to the Properties -> World tab, change the Viewport Display to black (0,0,0)
- in the “Surface” pane turn off “use nodes” (changes world surface color to black)
- change the render engine to Workbench
- hit numpad-0 to assume camera view
- use viewport shading drop-down to change background to “World”
…it’s clear that the “black” inside the camera frame is not pure black, but near-black. This is also the case if I do an F12 render: the background around the cube isn’t black, but a hash of near-black pixels.
Again, if there is an obvious setting to tweak that fixes this, apologies for the noise.
