           Summary: StarCraft2 bad physics issue on non-flat landscape
                    parts that is unrelated to the physics
           Product: Wine
           Version: 1.2
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-d3d
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: NightNord at gmail.com


I've attached few screenshots, illustrating this bug, first of which is most
impressive.

In short: at some parts of map, mostly this is non-flat and non-linear parts on
landscape, units, controlled by player or not, may:
1) Fly above the screen or just a little bit up.
2) Fall underground.

Buildings are also affected with even more funny effects (see first screenshot)

In most of cases units became unselectable with mouse and competely invisible.
Only way to get them out of there - move some big force at same location
(binded to hotkey), pushing them to outside of bug zone. I.e. "collisions" with
ground units just ok. Firing and damaging also works well, so only UI and
graphics are affected. No such bug for air units noticed.

This is done on ATI HD4570, fglrx-10.7, 2.6.35 kernel. wine-1.2 first tested.
Still remains on 1.3.

Settings:
VideoMemorySize=512 (unrelated)
UseGLSL=disabled (unrelated)
OffscreenRenderingMode=pbuffer (unrelated)

Game settings:
Shaders are low (middle with UseGLSL=enabled - unrelated. Without it
(UseGLSL=enabled) can't be tested due to bug #23906)
Textures are high (middle - unrelated)
Physics - middle (unrelated, I even tried to "off" it)
Shadows and other shader-related settings - low
Reflections - on (unrelated)

P.S. "Unrelated" means that changing this settings doesn't help, but no deep
testing was done (mostly due to crashes or heavy lags).

Default log shows nothing new while moving though such locations, so I'm not
posting any log.
