when I use these codes:
 RS_TextData textData = RS_TextData(RS_Vector(IED_RECTANGLE_LEFTTOP_X,IED_RECTANGLE_LEFTTOP_Y-(height*2/3)),RS_Vector(IED_RECTANGLE_LEFTTOP_X+IED_RECTANGLE_WIDTH,IED_RECTANGLE_LEFTTOP_Y-(height*2/3)),
                                       (height/3>IED_NAME_HEIGHT)?IED_NAME_HEIGHT:height/3, 1.0,
                           RS_TextData::VABottom,
                           RS_TextData::HAFit,
                           RS_TextData::None,
                           iedName,
                           "wqy-unicode",
                           0.0);
    RS_Text* text = new RS_Text(graphic, textData);
    text->setPen(RS_Pen(RS_Color(255,255,255),RS2::Width01,RS2::SolidLine));
    graphic->addEntity(text);
set style to "wqy-unicode" ,or any other style such as iso,unicode. librecad will run 100% cpu. Is there any thing should I do?
 however when I only add image  that is OK。 I think redraw graph is the problem.
my dev env is :
debian Debian GUN/Linux 7.0 (wheezy)
qt version :4.8.2.
