Yes you must use a wxPaintDC here, see below.

You must always create a wxPaintDC for the window you set a wxEVT_PAINT
callback for. This is because the wxPaintDC clears the "damaged" area set
by the OS, if you don't create a wxPaintDC the OS will call your paint
handler endlessly trying to get your app to repaint itself.
See here for a little more info.

I believe that creating a wxPaintDC is not strictly required in Linux which
is perhaps why the original code worked for its author.
