           Summary: Scrolling using the vertical scroll bar has become
                    more choppy with OpenGL enabled
           Product: LibreOffice
           Version: 5.3.0.1 rc
          Hardware: All
                OS: All

Description:
Scrolling using the vertical scroll bar has become more choppy with OpenGL
enabled

Steps to Reproduce:
1. Open attachment 136841
2. Set view to multi-page view
3. Zoom out to 4 pages
4. Wait until all pages are loaded (drop in cpu usage)
4. Scroll down by selecting the vertical scroll (left mouse click) slider and
move it up and down. 

Actual Results:  
Very choppy scrolling experience

Expected Results:
A bit more smoothed like before the identified commit. Without the commit is
'OK' but far from perfect compared to GDI


Reproducible: Always


User Profile Reset: No
