when i create a Parabola, the displayed curve exhibits a polyline like appearance most noticeable at the vertex, changing to degree 3 exhibits the same issue changing to degree 4 the issue disappears. tested in v7 and v8
testing further the same issue seems to happen in cp curves and interpolated curves, just very fine that one barely notices, changing to degree 4 seems to cure that problem till you change to a different (lower) degree again.
@stevebaer i can remember you talking about curves being displayed derived from actual triangles due to how the display pipeline was changed. i can not remember having such an issue in v5. though i believe there was a display simplification for curves or circles when panning.
Please post a sample file. Everything is broken down into triangles and sometimes we may not break down to a high enough level of detail
there you go, i drew a straight line below each curve marking the boarder of my viewport where the issue is exhibited best. i am using a 4k monitor set to emulate 2304x1536, the issue is least shown in the interpolated, there it is barely visible. the cp point shows it a bit less then the parobola but still plenty. the parabola is strongest visible.
