Я рисую вот как:

procedure TfmMain.ClientWndProc(var Message: TMessage);
var
Dc: hDC;
Row: integer;
Col: integer;
begin
with Message do
if UsePictureAtBackground and (Msg = WM_ERASEBKGND) then
begin
Dc := TWMEraseBkGnd(Message).Dc;
for Row := 0 to ClientHeight div imBackground.Picture.Height do
for Col := 0 to ClientWidth div imBackground.Picture.Width do
BitBlt(Dc, Col * imBackground.Picture.Width,
Row * imBackground.Picture.Height,
imBackground.Picture.Width,
imBackground.Picture.Height,
imBackground.Picture.Bitmap.Canvas.Handle, 0, 0, SRCCOPY);
Result := 1;
end
else
Result := CallWindowProc(FPrevClientProc, ClientHandle, Msg, wParam, lParam);
end;
