Row height should shrink to the minimum height required to display concurrent Tasks within the current viewport (i.e., zoom range extents when zooming/scrolling horizontally.) This will significantly reduce the amount of vertical scrolling required on the Gantt Chart when including multi-capacity Resources that have high numbers of concurrent Tasks at certain moments on the timeline, but not within the current viewport.
The functionality has been enhanced in Orchestrate version 7.83. Please upgrade to this version or above.
