[Langbart]

An issue was reported via IRC 0ad-dev ​28/May/22

07:09 < Freagarach_afk> No, that I see the terrain and territory lines in SoD.
07:11 < Freagarach_afk> It seems it depends on the map also.
07:11 < Freagarach_afk> With some terrains it is more visible.

to reproduce

• Switch to GL ARB backend
• Restart the Game (Make Sure Smoothlos is on)
• Open Acropolis bay,
• move around and notice everything is black.
• Open the dev overlay
• Reveal Map, and hide it again.
• move around and notice everything is still slightly visible.
