Scrolls 1 slide at a time using the mouse scrollwheel. Grabbing the slider is normals as well. I don't understand the problem.

Sorry, I completely forgot to mention:  This is with a laptop's touchpad.  I just tested with a normal mouse and it works as you described.

It is also not a problem of having a super-sensitive touchpad: in other applications the scroll speed is appropriate.

I guess we could close as dupe, even though this is Linux

Sigh, I did not notice the other report has meta "Win-Touch". Let's keep this separate, then.

I reproduce the problem with LO 6.4.3.0+ built at home under Ubuntu 18.04 x86-64 with Gnome DE. Even if I set the speed of the touchpad equal to the speed of the mouse, the scrolling with the touchpad is very fast comparing what it is with the mouse.

I also have this issue.

Also a very similar issue occurs for me (not only in Impress, but in other LibreOffice applications too) when trying to change view zoom with Ctrl+scroll: it also scales in and out uncontrollably fast.

(This may be connected with the fact that touchpad driver emits some kind of continuous scroll events? It is almost as if LibreOffice detected the number of events without taking into account their «scrolling amount»…)
