    Description

      The attached example calls QQuick3DGeometry::update() by 30Hz interval
      and feed 1MB dummy vertices. The rendering performance is getting worse
      until the QQuick3DGeometry instance recreated.

      Apparently the subsets count increases indefinitely. I'll send a patch shortly.

          • P1: Critical - Urgent and Important, will STOP the release if matched with set FixVersion field. This includes regressions from the last version that are not edge cases; Data loss; Build issues; All but the most unlikely crashes/lockups/hanging; Serious usability issues and embarrassing bugs & Bugs critical to a deliverable.
