Confirming in wine-1.6-rc5 although native gdiplus stops any of the previews from displaying.
'winetricks windowscodecs' got the previews working for me with native gdiplus again.
With wine-1.9.6-66-g329dfee, I don't see any difference in the tab previews with native gdiplus (plus windowscodecs) compared to the builtin one.
