From point of view of rendering, each dash is an independent object. So the drawing has more than 140 3D-objects to be rendered. You get faster rendering, if you set anti-aliasing off.
Moving to NEW and reducing importance considering the number of points in the cube
@Lubos As you are optimizing Skia for polygon and images.. etc you might be interested in this one too; some day. Bug is around a long long time already, so can wait Massive amount of time spend in drawinglayer::processor3d::CutFindProcessor::processBasePrimitive3D Or at least based very sleepy (often slightly off) Probably re-rendering the full shape 3D over and over on scroll-zoom (similar to images I speculate). Feel free to ignore :-).
