Blender Version
Broken: version: 2.82 (sub 1), branch: master, commit date: 2019-10-24 19:11, hash: rB2a3b5dc73038
Worked: (optional)

Short description of error
Grease pencil has weird edges when put over a Camera Background Image (it doesnt happen over an image texture)

Exact steps for others to reproduce the error
Create a new 2D animation file
drag and drop an image to the viewport to get it as a background image
draw on top of it.
see the white borders around the drawing?, its much worse when the strenght of the pencil is driven by pressure or when the strength is not 100 percent.

here are some samples

@Antonio Vazquez (antoniov) : should we merge this into T66293 then?

note: at the current state of https://developer.blender.org/diffusion/B/history/greasepencil-refactor/ (rB84bf68186dfe) this does not seem to be solved there...

@Philipp Oeser (lichtwerk) Not sure. I keept this task because I don't know if this must be fixed in GP Drawing Engine or it's in other drawing areas.

@Clément Foucault (fclem) What do you think?

BTW: The refactoring is in progress and still a lot of things pending.
