Fonts

GDI+ supports only True Type Fonts. When using a font that is not a True Type Font, GDI+ will not be used. Furthermore, when drawing strings with a transformer, to draw a vertical string for example, the result may not exactly match the rendering done with GDI. This is because the rendering engines used in GDI+ and GDI are not exactly the same.

Brushes

The Windows HATCHED patterns are not exactly mapped to the GDI+ HatchStyle. Thus, switching to GDI+ may change the drawing of the pattern slightly.

Arcs

Flat arcs are badly drawn by GDI+. Thus, GDI+ will not be used to draw flat arcs.

Draw Mode

GDI+ does not support any other mode than IlvModeSet. For example, when using IlvModeXor, GDI+ will not be used.

Windows XP Look and Feel

Transparency and anti-aliasing are not available with gadgets drawn using Windows XP.
