hi,
for current version babylonjs 4.2.0-alpha.27, i found the GUI may conflict with edgesShareWithInstances setting.
when enable edge rendering, and enable edgesShareWithInstances , then do mesh.createInstance,
the GUI will disappear. Example below:

think it’s a bug , but maybe there are some setting i need to make to make them work at the same time?
