We need to display large rasters on the map with lots of fine detail that needs to be viewed up close. We have tried using ElementLayer and GraphicsLayer (with an imagebrush fillsymbol). Both approaches work fine at high scale, but both exhibit the same bug, that whenever you zoom in far enough, the translation and scale of the UIElement shifts suddenly. This behavior can be observed even on the interactive sample for ElementLayer. If you zoom in on one corner of the red rectangle far enough (in Africa), eventually it will move into the wrong position. Surely this has been identified before; I just wonder if there are any workarounds available or fixes planned?
