Looking for latest on Visualizer issues with bar labels and logic lines in Gantt chart

I just spent 30 minutes in the knowledge base and community forum looking for the latest information on Visualizer issues I am having with the location of bar labels, logic lines, and the definition of critical logic lines. Cannot find anything that is recent.

Labels are associated with the first bar in any row.

Logic lines are drawn to the first bar in any row.

Critical logic lines seem to define critical as Total Float.

Does anyone have the latest on these issues?
