...of course, given the status of plain C API of gdiplus by Microsoft, there's a chance it's only reproducible only with C++ API and PointF& version of DrawString calls.
There is no such a thing as C++ gdiplus API.

With my hack, the string is drawn, without it - not. Now, a result from Windows is necessary, but even I was registered on WineTestBot (which I'm not), with this code there's only eyeball test.
You need to write the tests and run them under Windows before you'll start to play with them under Wine, otherwise it's pretty easy to confuse yourself with controversial results.
Probably bug 34102 is a duplicate of this one, but it's hard to tell since it was never clear in this bug what it is about.
