Description

The Annotation Editor needs to much time to update the displayed text with annotations when the annotation model behind it is updated. The implementation right now triggers a repaint for remove and add AnnotationFS operations and two repaints for an update to an existing AnnotationFS.
These repaints can take around a second on a newspaper article which is visualized with all token annotations. This huge delay makes the Cas Editor nearly unusable.
