Hello,

when viewer sets to 2D and mapMode2D:ROTATE, draw a polyline and pan, ends of the line are flickering.

Research direction

Start by reproducing the issue from the linked Sandcastle example: switch the viewer to 2D with mapMode2D:ROTATE, draw a polyline, and pan. Trace the polyline rendering path involved in that example; done means both line endpoints remain stable without flickering during panning.
