Description

Bei Smooth ROIs flickert Mesa, d.h kurz aufflackernde schwarze oder rote Linien zwischen den Kontrollpunkten, siehe Video.

Es handelt sich um einen bekannten Bug in der MESA:

New remote branch pushed: bug-14146-Mesa-Flickering

braucht laut Markus kein Core Modification flag.

Reopen for commit of rebased branch for master merge

New remote branch pushed: bug-14146-mesa-flickering-rebased

[90865d]: Merge branch 'bug-14146-mesa-flickering-rebased'

fix mesa roi flickering by use of line_strip

The fix has been merged into master now.

The flickering effect could not be reproduced.

I just looked at the code: did you verify that the code is not called with an empty line? Otherwise

vertices.begin()->Point

could potentially crash.

Should be no problem, as it is only called if planar figures has been marked as "closed" object.

Also PlanarFigures, like our PlanarPolygons or PSubdivisionPolygons, have 2 or 3 control point per initialization.
