FS2024 1.4.18.0, never seen these… runway length, equally spaced, faint white lines?
Not sure what is happening here, those white lines seem to exist whether runway material, ground merging, coloration is on or off, or which material is selected, or if there is or isn’t any aprons or poly beneath it. I tried turning off the runway markings and every other runway options, to no avail as well. Even played with the terraforming falloff distance without luck
