I have wine 1.4.1 and have this bug as well. Certain units and buildings cause the game to slow down more than others. If a building is idle (i.e. not building or upgrading anything) the lag is negligible. If the building is highly damaged, then the game slows down some. If I select an enemy unit, their is almost no lag. If by chance I have no unit selected (maybe the unit I had selected died), the game runs smoothly and quickly, better than on Windows. The effect is worst when I select units or a building that is actively building a unit or upgrading.
This bug isn't present when I run the game on wine version 0.9.14 (there is a bug with the sound however). Also my graphics card is ATI Radeon Xpress 1100 and the driver is Gallium 0.4 on ATI RS480.
