[bthieurmel]

When network have "self-loop" edge (from = 1, to = 1), they are not always showed, depends of movement :

Can you provide a minimal example showing the problem via jsbin.com. Please also let us know how to reproduce the error using the example.

Short example : http://jsbin.com/fipaha/edit?html

Seems to be with dot shape. Edge from node 1 to node 1 is not always visibled (clicking Nodes / moving nodes, ....)

I can confirm this bug. It works with 4.17 and breaks in 4.18. Thus, it was introduced in 4.18 :(

Not only for dot, observed same bug with diamond. Don"t have test all shape...

For me, the issue can be seen:

• when opening the network, the link-to-self loop is missing... and then simply clicking on the canvas displays the loop.
• moving the node with the loop disappears the loop, then clicking on the canvas shows it again.

must be related to drawing that edge...

The code in network/modules/components/edges/util/EdgeBase.js lines 60, 61; 86, 87; and 101, 102 is where the loop circle is getting drawn... looks like _getCircleData is a potential culprit.

And moving others nodes without loop then loop flash

I've got a fix for this one... I'll be doing a PR shortly.
