Thanks, the image is helpful, we will try to reproduce. My initial guess is that this have something in common with windows scaling and potentially resolution setting.
Update:
It is caused by the low resolution (probably 1200x675), can you make it higher?
As a work around you may "restore" the main window and "maximize" again
another option is to re-layout the panes, you can drag and drop the "Connector Dock" pane by dragging the "Connector Dock" text
