<p dir="ltr">I guess iT is a resampling question.<br>
My theory is that you dont see this issue with on polygon filled
with solid color because the resample strategy find the same color
in all the considered portion of polygon.<br>
This is not true for labels or lines.</p>

points and with other colors.<br>
Not only black.</p>
