Hello, I think there is a bug in the text rendering in an overlay layer. Under OCC 6.4.0 and up (OCC 6.5 include), when I use V3d_View::ColorScaleDisplay(), a color scale is displayed on the side of the view. If I move an opaque shaded face that overlap the colorscale, the text goes under the face (become hidden by the face), but the color scale itself behave correctly. This was working perfectly under OCC 6.3.1. I notice that since OCC 6.4, the text rendering is done using FreeType and FTGL. Does anybody have the same problem? The application is running under Windows XP 64. Thanks, Francois.
