non fully opaque drawn twice at stops with pencil tool

Description
Created attachment 347239 top drawn with 6 clicks, bottom with two. Both have too dark half-transparent pixels
How to reproduce:
- use pencil tool (shortcut 'p')
- select a small brush size (used 1.5) and the non-blurred brush, should also be reproducible for all others, but is less visible then
- click on a pixel with left mouse button. Hold shift, select some pixel to the right to draw a horizontal line
- redo the above step to effectively elongate the horizontal line
What happens:
- at the intermediary step the half-transparent pixels are actually drawn twice, i.e. they are darker
What should happen:
- the resulting line should look exactly like when drawn in only one step, i.e. don't let the intermediary stops of the polygon be darker
See also attached picture: Top: Line drawn with 6 clicks, i.e. 5 intermediary stops / polygon points Bottom: Line drawn with only two steps
P.S. The left side of the bottom line also has that bug, i.e. the left half-transparent pixels are also darker. The line looks jagged, even when zooming out! It is quite straining to correct this bug on every line I draw
