This doesn't contain needed details: what card, driver, what non-default Wine d3d-related settings and overrides (if any).
nVidia 8800GT, 177.13 beta driver, no non-default Wine settings and overrides (but TF2 running with -dxlevel 81 as needed to actually play the thing at all).
This does not appear to be an nVidia related bug, as someone has suggested to me that they have a similar issue with an ATI card.
