A much better way to do font rendering in Wine is to use the new client side rendering code. For this you need an XServer capable of supporting the RENDER extension (xdpyinfo will tell you whether you have such a beast) and a copy of the FreeType library version at least 2.0.5 (but the later the better). Add a [FontDirs] section to your ~/.wine/config file, with entries pointing at any directories that contain TT fonts...
This got me to try out the client side rendering. It really does make the fonts (in MS Word in particular) not suck! Nice job. Guess I will stick with this configuration.
I came across two issues. The first is that virtually all dialogs and some windows were being drawn too narrow. The window/dialog height was normal. Looking at traces with and without the client side rendering, I saw this difference:
Server rendering: trace:dialog:DIALOG_ParseTemplate32 DIALOG 0, 0, 287, 165, 0 trace:dialog:DIALOG_ParseTemplate32 STYLE 0x80c820c0 trace:dialog:DIALOG_ParseTemplate32 EXSTYLE 0x00000000 trace:dialog:DIALOG_ParseTemplate32 CAPTION L"Open" trace:dialog:DIALOG_ParseTemplate32 FONT 8, L"helv", 0, FALSE trace:font:WineEngCreateFontInstance L"System", h=16, it=0, weight=400, PandF=22, charset=0 orient 0 escapement 0 ... trace:font:XFONT_GetAvgCharWidth retuning 6 trace:font:XFONT_RealizeFont physfont 3 trace:font:GetTextMetricsW text metrics: Weight = 400 FirstChar = 0 AveCharWidth = 6

Suspecting the average char width, but not understanding the code that generates it, I cheated. In WineEngGetTextMetrics(), I added: if (ptm->tmAveCharWidth == 4) ptm->tmAveCharWidth = 6;
And this fixes all the dialogs and windows for me.
The other problem I ran across is shown in these pictures, showing server and client side rendering. My little hack above had no effect on this particular problem. http://www.leewardfpga.com/server.png http://www.leewardfpga.com/client.png
As can be seen, the vertical text is getting chopped off slightly.
The font with the problem is Tahoma, and this is with a ~/.wine/config that contains
[fonts] "Resolution" = "96" "Default" = "-adobe-times-" "DefaultFixed" = "fixed" "DefaultSerif" = "-monotype-times new roman-" "DefaultSansSerif" = "-microsoft-tahoma-"
