Workaround

The workaround for this issue is to change the code for the drawing of the custom layer. This avoids the problem and will ultimately improve the overall performance of the application:1. Set the Layer.Cached property to true.2. Get the ScreenCacheId of the newly cached layer.short cacheId = axMapControl1.ActiveView.get_ScreenCacheID(esriViewDrawPhase.esriViewGeography, featureLayer);3. Refresh only that cache:m_mapControl.ActiveView.PartialRefresh(esriViewDrawPhase.esriViewGeography, cacheId, null);For even better performance use IViewRefresh instead.
