QuestionWhy does GDI+ DrawString punch holes in the alpha channel? Pin

Hello folks!

I got an annoying anomaly with GDI+ i just can't understand. I created a 32 bit bitmap in memory, did some drawing on it and used it to display a layered window. This all works well except for one thing. I use Gdipluss::Graphics::DrawString to render some text onto this bitmap which seems to erase the alpha channel on the bitmap everywhere where letters of the text are drawn. Here's the simplified code i use:
...
  Gdiplus::Graphics     Gx(MemDC);
  Gdiplus::SolidBrush   GxTextBrush(Gdiplus::Color(0, 0, 0));
  Gdiplus::Font         GxFont(MemDC, &LFont); //LFont is a LOGFONT and it is initialized to the default GUI font.

  Gdiplus::RectF TextRect;
  //... init textrect to the correct position...

  Gdiplus::StringFormat GxFormat;
  //... set GxFormat to the needed values...

  Gx.DrawString(text, textlength, &GxFont, TextRect, &GxFormat,  &GxTextBrush);
  ...

Changing the GxTextBrush's color by adding an alpha component of 254 "fixes" the problem, but adding 255 produces the holes again, also making the font bold (LFont.lfWeight = FW_BOLD) seems to fix the problem also... so could someone please tell me what's the logic behind this? For now i set the alpha to 254 and go on with it...
Thanks for any light-sheding attempts in advance.
