Character close view

This strange effect persists with any possible configurations (including those
in gfxoptions debug menu). It's followed with dozens of 
fixme:d3d_surface:IWineD3DBaseSurfaceImpl_Blt Filters not supported in software
blit
messages, but I'm not sure, that it's directly related to the filters missing,
but I've tried to comment-out render-target check, so direct opengl
implementation of blit called always - it seems to gone, but this was unstable
and in any following runs I've got completelly black scene, including mini-map
(effects, selections, magic spells and soon - all in place, but all surfaces
are blackened).

I'm attaching screenshot of player's character, close view and far view. You
may see some dotted patterns on characters clack, or on terrain around him.
This effect hard to get screenshoted as it's mostly visible while moving
camera, mouse, character and soon.

It's might be related to other bug, that affects only indoor areas, that I'll
post soon also.

Tested on:
wine-1.3.3
kernel 2.6.35 with 'nopat' kernel option
ati-drivers (fglrx): 10.9, ATI Mobility Radeon HD4520

Wine direct3d configs:
OffscreenRenderingMode=fbo
VideoMemorySize=512
UseGLSL=enabled

Overrides and installed packages:
vcrun2005 and d3dx9 from winetricks (without this game just can't start due to
unimplemented features).
devenum.dll and dxdiagn.dll (without this, game can't find any video device and
refuses to run).
