--- Comment #2 from EG Galano eg.galano@gmail.com 2010-12-13 19:49:06 CST --- To reproduce this, you need to load into the game past the main menu and character creation screens.
Pick a family and move into a residence. Once you are within the game's 'living' play-mode, the rendering issues occur as you pan around any scene such as the outdoor scenery near your house.
To install the game properly, use wisotool available at http://code.google.com/p/winezeug/source/checkout
