In the most recent release Calc navigation performance has degraded significantly from earlier versions.
Steps to Reproduce:
1. Open a spreadsheet worksheet with more than 100 rows
2. Scroll down or up using any method (mouse roller, vertical scroll bar, arrow keys)
Laggy scrolling, very difficult to get to the cell you want to get to.
Scrolled smoothly and quickly.
