Libreoffice draw connector is not shown during the drawing

I’m using libreoffice draw and I have some problems with the lastest versions:

  1. in the past versions of libreoffice when I drawn a connector between two object the edges of the connector rest snap to object point, while in the lastest versions it doesn’t happen;
  2. when I try to move the connector (not the object) the connector is not shown during the movement
  3. the connector is not aligned to the grid even I have set it.

In this way using the connector is really cumbersome.

do you have any advice?

thank you in advance.
