--- Comment #18 from Mateusz m.jedrasik@gmail.com --- Ah, sorry, hasn't fixed sh*t; I just clicked a non city unit so the textures were seen; like someone else wrote here, when there's no cities or settler units, then there's backgrounds visible.
Alright then, I also have this bug present, in all possible versions of wine that I thus far tried!
Come on wine, how long has this regression been about for now, 3 years almost.
