I installed Windows in a virtual machine last week because it saves
time rebooting when I use it so infrequently, and was surprised to
discover that the font rendering used in Chrome's web page display
frame was greyscale and not ClearType/subpixel like the rest of
Windows. I don't use Windows frequently enough to comment on whether or
not this has changed.

I've tried various combinations of filters and settings for my font
rendering, and all subpixel rendered text (even on OS X) looks slightly
off; some letters have colour fringes, some letters are a slightly
different colour to others, and it can be quite distracting. Maybe it's
different with font hinting set to a higher value; I always opt for
'slight' or 'none' because I prefer the smoother shapes over the more
pixelated look of Windows.
