Public bug reported:
Steps to reproduce (20.04), shell 3.36.1:
1. Open 'Show Applications' -> 'All'
2. Attempt to scroll through the pages using a touchpad.
Expected result:
Scrolls through pages of applications one at a time.
Actual result:
Scrolls to second page of applications but will go no further.
This happens whether two-finger or edge scrolling is used.
Using an actual mouse with a scroll wheel works as expected. Using this in
conjunction with the touchpad reveals horribly broken behaviour:
- Clicking on the 'dot' for any of the pages will let the touchpad scroll at
most one page in either direction, if the mouse is not moved
- Moving the physical mouse lets the 'momentum' of the touchpad scrolling
advance the list further as expected.
Incidentally, the application menu doesn't honour the 'natural
scrolling' setting for the touchpad in the mouse settings - I will file
a separate bug report for this but it may be of interest for whoever
looks at this.
