I use ISnappingEnvironment in my custom tool for ArcMap 10.3.
The first time I draw a new point (click on a map) - I see a delay (about 3 seconds) and graphics (point and label(text)) disappear.
Next points appears with milliseconds on the screen.
If I close/open my tool I DO NOT see that delay - meaning it is once for an ArcMap session. If I close/open ArcMap I can see that delay.
I draw a point on MouseUp(), but initialise a snapping environment earlier.
The first point is not snapped to anything.
So why it is delayed only for the first time?
Thanks for any help.
