Creating arrows between elements has a huge performance burden #179
Description
The code at this line is called many teams every “tick” when dragging from a shape with A pressed (to create an arrow). In my profiling session it was called 7 times every tick.
Most passes through that code cause a 20ms delay, which pretty quickly sum up to 100ms and jagger the UI.
There’s some cacheing opportunity here. How could I help?
