I had successfully tracked this bug down a bit.
Looks like this bug is fonts-related and somehow complicated.
In case you've got no "Tahoma.ttf" available either fontconfig-wide,
Xfs/Xorg-wide and Wine-wide (i.e. inside WINEPREFIX and /usr/share/wine/fonts),
and you had provided a reasonable substitute to it using Wine's registry (for
example "HKCU\Software\Wine\Fonts\Replacements\Tahoma" = "Liberation Sans")
then the rendered font still would be non-ideal, but at least italic subtitles
would not be "clipped". I would attach example screenshot I had taken couple
minutes ago with wine-1.2-rc4 shortly afterwards.

Removing wine's font replacement and using wine's version of "Tahoma" (i.e.
"tahoma.ttf" and "tahomabd.ttf" from "/usr/share/wine/fonts") leads to a
problems with font rendering in menus like ones that were attached to this bug
in comment #6. Also all subtitles with italicized got clipped on the right side
of each letter.

Having original MS version of Tahoma installed either system wide or inside
related WINEPREFIX seems to "almost fix" font renderings in menus (there still
are some rendering glitches that might be considered bugs), and clipped italic
subtitles also present.

No matter which version of "Tahoma" is used adding wine font replacement like
"HKCU\Software\Wine\Fonts\Replacements\Tahoma" = "Liberation Sans" fixes the
displaying of italic subtitles (as shown at attached screenshot). Still the
font seems to be cripped (what had happend to the font smoothing?) and I doubt
if it is rendered with the correct color.

Inspecting the contents of the "HKCU\Software\Wine\Fonts\External Fonts"
registry key shows that the original Tahoma font haven't got pre-cooked TTF
files for both "Italic" and "Bold Italic" (tahomai.ttf and tahomabi.ttf) and it
looks like this is the key point that triggers this bug. Having replacement
font defined for Tahoma makes wine use tahoma.ttf/tahomabd.ttf for Regular/Bold
Tahoma, while using LiberationSans-BoldItalic.ttf/LiberationSans-Italic.ttf
replacements for "Bold Italic"/"Italic" Tahoma.
