Sorry for my lack of terminology here as I am new to ArcGIS and ArcObjects.
I have managed to create a point feature and plot it as so:
IFeature feature = layerFeatureClass.CreateFeature();
IPoint p = world;
feature.Shape = p;
//Invalidate the area around the new feature
editor.Display.Invalidate(feature.Extent, true, (short)esriScreenCache.esriAllScreenCaches);
However, the point is rendered very small in arcmap until I cause a full refresh, then it draws it as it should.
Looking at the feature extent, the width and height is 0, which makes sense since it is a point, but I am wondering if this should be higher for the redraw since the point being plotted is not a single pixel?
If I change it to
editor.Display.Invalidate(null, true, (short)esriScreenCache.esriAllScreenCaches);
The point renders properly, but I am properly redrawing a lot of features that don't need redrawn in the process.
Here is an image of whats happening
