I've spotted a weird bug.
When this point is the start point it colors the pixel black.
Set another point as the start point and the appearance is as expected.
Another fix: draw a second contour...
see screenshots :)
oh, cool bug, will look into this issue :)
mm, seems to be a bitmap drawing bug: a single contour with a ttf-preferred-contour direction will draw this bug. I fixed it with a small detour.
This bug also appears in the SpaceCenter. This is the same thing?
