I found the problem. The program does the bitblitting of the picture's itself,
and is not much helped when wine erases the picture right after that.

I fixed the same bug years ago:

        * controls/static.c: Rein Klazes <rklazes at xs4all.nl>
        When repainting a static control, with SS_BITMAP style, do not erase
        the background. Keep sending the WM_CTLCOLORSTATIC notification as
        Windows does.

but regressed:

commit 1de825f746c6f4873a54ab21c16d728695c9a1e8

    static control: SS_CENTERIMAGE fixes.
    - Stretch bitmaps and icons to the whole control size if
      SS_CENTERIMAGE is absent
    - Draw the background of centered bitmaps and icons with the
      background brush (like Windows XP for applications with a manifest)

I will have a look. Testcase is clearly needed.
