           Summary: Several graphical corruptions in Railroad Tycoon 3
           Product: Wine
           Version: 0.9.30.
          Platform: PC-x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

There are several graphical corruptions when running Railroad Tycoon 3 under Wine.

1. Distorted water reflections are not drawn

This is a screenshot of what reflections look like under Windows:

A screenshot of the game under Wine and the WINEDEBUG=+err log follow below.

2. Detailed ground textures cause heavy flickering

It appears as though the detailed textures are drawn as additional polygons
slightly above the lowres-ground model. The flickering looks like the
"classical" z-buffer error, where polygons are sometimes rendered above and in
the next frame below the ground.

3. The overlay in the minimap and in construction menus is not transparent

The camera direction is drawn as a gradient transparent polygon on top of the
minimap in Windows. Under Wine, this polygon is opaque. Same applies for the
selections in the construction menu.
See screenshot below.

4. Menu selections are hidden under a black box.

In the settings menu, the selected item is obscured by a black box. See screenshot.


The test system has an NVIDIA 6800 GPU and is running the NVIDIA UNIX x86_64
Kernel Module  1.0-9746.
