The problem is that the application leaks an object created with GdipCreateSolidFill(), and built-in gdiplus always creates a GDI brush for such an object. Most likely native gdiplus creates a GDI brush only when needed.
Artem, you may want to report this leak to LibreOffice developers, but it's also a valid Wine bug.
I once filed a bug report against OpenOffice two years ago (it's still not solved). Zero comments, nothing, no activity. I guess I will refrain from waisting my time again.
