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
Client 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"helv", h=-10, it=0, weight=0,
PandF=00, charset=1 orient 0 escapement 0
...
trace:font:WineEngGetTextMetrics OS/2 winA = 1854 winD = 434 typoA =
1491 typoD = -431 typoLG = 307 FT_Face a = 1854, d = -434, h = 2355:
HORZ a = 1854, d = -434 lg = 67 maxY = 2124 minY = -665
trace:font:WineEngGetTextMetrics xAvgCharWidth 904 x_scale 20480
tmAvgCharWidth 4
trace:font:GetTextMetricsW text metrics:
Weight = 400 FirstChar = 32 AveCharWidth = 4
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.

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-"
