We use the Gantt widget as part of our product. Recently we have used the Roll up feature to render Milestones. We are seeing :
- Some of the Milestones do not appear on the Gantt
- Milestones flicker when we scroll
- Also some of the Milestones disappear during the scrolling (though they are very much on the view port)
We ran our use cases with smart rendering off and then the problems disappeared. Is there any known issue for this ?
