Created attachment 54820 [details] Screenshot
On testing this again with Wine 1.9.12 the issue does not look anymore like in the old screenshot (maybe the terrain got there updated?). But if you look at the edge of the terrain you still see the water showing through the ground a bit. In the attachments is a new screenshot that shows this.
Could you retest with more recent wine? We are currently using wine 2.8. Also if its not fixed yet, this bug would need some game logs.
