I made a sweep cut that follows a sketch trajectory designed externally to the feature.
the detail is displayed incorrectly as in Annex 1.
if I also perform a small cut on the external profile (Annex 2) the display is right.
never happened a similar problem, however I think it is very difficult that it is a video card problem (if it were a problem regarding the video card should disappear or vary by zooming or rotating the model)
