[B18] river on Worldmat is invisible

[seffire13]

Good day,

I wanted to start a new game and happen to notice that I see no rivers and no roads on the worldmap.

I found somewhere on the internet, that I should update my Intel HD drivers, which I did but I still can't see rivers on the worldmap.

I even deactivated all my mods and let the game create a new log_file afterwords, but no results.
I hope I attached everything that is necessary, and the seed of the map was/is "butterfly".

Good day,
Seffire
