  I have now found a solution myself:

  procedure TLMDGlyph.UpdateMaster;

  var
    done: Boolean;
    BMP: TBitmap;// BS 17.07.2025
  begin
    done := False;
    if Assigned(FOnGetBitmap) then
    begin
      FMaster.Assign(nil); // Clear for sure.
      FOnGetBitmap(Self, FMaster, done);
    end;
    if not done then
    begin
      if FGlyph.PixelFormat = pf32bit then // BS 17.07.2025
      begin
        BMP := TBitmap.Create(FGlyph.Width, FGlyph.Height);
        try
          Bmp.Canvas.Draw(0,0, FGlyph);
          FMaster.Assign(Bmp);
        finally
          Bmp.Free;
        end;
      end
      else
        FMaster.Assign(FGlyph);
      FMaster.AlphaFormat := afDefined;
    end;
  end;

  Your bitmap is a 32bit bitmap with alpha-channel. Bitmap's alpha-channel contains only zeros, so it's fully transparent. As a result, it correctly shows as fully transparent (invisible).

  
  

  I've converted it to 24bit bitmap without alpha-channel for you using free PixelFormer image editor.
