Some text-shadow rendering bugs (Chrome 17) about mactype HOT 3 OPEN

for picture 1 and 2, it will be appreciate if you can provide website url or 
the name of software.
for pic 3&4, I have to say that mactype will never be work like gdipp did. 
MacType has a very different render conception from gdipp that mactype always 
place letters as windows GDI did, we are looking for accurate GDI simulation 
because this will make mactype extraordinarily compatible with apps, and it 
won't broke the WYSIWYG of Microsoft Office products. 
While on the other hand, gdipp rearranges characters using its own algorithm, 
which makes text rendering feels better but also become incompatible with lots 
of apps.

Thank you for the answer!
Picture 1 is Soundcloud.com widget, appearing on many sites (particularly this 
one cam be seen on http://paperpaper.ru/jack_white/)
i figured out that the very css rule causing a mess is this one:  {text-shadow: 
rgba(255, 255, 255, 0.898438) 0px 1px 0px;
body - 0 1px 0 rgba(255,255,255,0.9) }
Picture 2 is zvooq.ru site, you can’t get there and view pages without some 
registration mess, but I think you needn’t as the problem is just the same.
