Description:
Scrolling is jerky or doesn't happen. I am using a trackpad. Selecting cells is slow. I am using a trackpad. The problem is not present in 7.5.8.2 but is in all later versions of 7.5 that I have tried including 7.5.9.2. I think it is not present in some versions of 7.6.

Steps to Reproduce:
1. Try to scroll in a Calc spreadsheet by dragging using two fingers on a trackpad.
2. Try to select a set of cells by dragging using three fingers on a trackpad.
3.

Actual Results:
Scrolling action resulted in delayed or no scrolling. Selecting resulted in delayed selection or occasionally individual cells being moved to another location in the spreadsheet.

Expected Results:
Smooth scrolling, immediate selection.


Reproducible: Always

I tried an ancient wireless mouse. Everything worked as expected except it didn't seem to be able to scroll horizontally.

I tried running in safe mode and the problem persisted.

Reverting to 7.5.8.2 cured the problem.

I believe I tried a version of 7.6 and everything worked as expected. I would have to retry if confirmation is needed.
