Preview graphic error [SOLVED]

anyone ran into this situation before? Plan and sections are fine. In perspective, the dots previewed are shifted away from their real positions. In the screen shot I clicked on the point in GH and clearly the gumball indicates where the point should be. Yet the previews (small white squares) are all off to the side…

use point preview flavor “cross”.
dots and circles are bugged

Turning off “Bump Preview” will likely resolve this:


great it works.
however all my Brep edges disappear on no bump preview. I can live with crosses for points.

Indeed, this tends to get exacerbated when modelling smaller objects at larger units (or not to scale). So for instance, modelling a staircase in meters might be the culprit in these rendering issues.
