This issue is related to KOGITO-764 feature. This guided tour feature observes user behavior. If user behavior is too different from expected one, the guided tour stop and ask user if he wants dismiss or continue.

The issue is if user decide to continue, then the guided tour window is restarted properly but position always into the center of screen.

As the guided tour window can not be dragged manually (it is positioned always automatically), it can happen guided tour overlay a node, that user need interact with.

In the attached screenshot user is asked to rename input node to 'Age', however input node is hidden by guided tour.
