When Labeling closed polylines with "Label position" parameter set to left or right and a value for "Label offset" parameter, some label feature texts overlap the polyline or are offset more then others (visualy).
I got a workaround for this by setting "Label offset" to 0 and using the Offseter transformer to Polar coordinates Mode, Distance by Conditional value: 0-90 half the label height, 90-270 the label height and 270-360 half the label height, and Polar angle set to @Value(_parallel_rotation)+90. Actually, the label height plus something to clear the linewidth.
It would be nice to have this implemented in the transformer.
