I am trying to get waterlines visualized with arrow lines, but when zoomed out I can't get them to be spacious enough.
So as you can see on the markerline settings, i set 100 pixels as an interval, but there are awkward clusters and even if i set it to 1000, they will not get more spacious (red dots).
I have the layer in edit mode so you can also see the vertex density (the red Xs).
Any ideas how to make the interval regular and more spacious?
