The Dark Spire (U) - Map and Wireframe rendering issues

Map does not render when pressing Y, although it does render when going to the main menu and selecting the Map option.

Switching rendering modes while in Y Map screen makes it appear, albeit with some differences between OpenGL and SoftRasterizer mode. It seems that the wireframe dungeon is being rendered undernearth/behind the Map, which is slightly transparent in the SoftRasterizer mode, it's a little hard to see but it's there.


This is further supported by the fact that switching the rendering modes back and forth quickly results in this:

...or sometimes this??? (the right half of the screen seems to be rendered on the left and vice-versa)

In Modern mode it's just a black screen:

Wireframe rendering in OpenGL:
around a corner (wall in front and right of it are missing)

looking at a corner wall (wall in front and right are missing)

looking at a wall (all walls missing)

Turning results in a series of random individual pixels being rendered each frame:

Wireframe rendering in SoftRasterizer (note how lines aren't in the correct position):



Without line hack:

Y Map workaround doesn't work

Let me know if any further info is needed.

Edit: Additionally, someone spotted that setting 3D renderer to None makes the Y Map work.
