--- Comment #5 from Adam Bolte abolte@systemsaviour.com --- I can confirm this is still an issue for me, at least with amdgpu and Mesa.
Honestly, the section of the map where I load my save game for testing (somewhere on a hill I think), the lines fill the sky so much that I can hardly see where I'm going. Far worse than the attached screenshot as the game is completely unplayable at this map location.
