Description Severo Raz 2017-02-14 20:14:59 UTC
When I try to zoom using two-finger scroll on my touchpad on any LibreOffice application, the zooming is barely controllable and hardly ever lets me get to the level of zoom I want. 

It feels like there is a zoom factor that is incorrectly calibrated so very thin scrolling on the touchpad becomes very coarse zooming on the application.

I expect that this problem is isolated to only some touchpads.

Bug 101388 seems to address a similar issue, but for two-finger scrolling in general. My computer is also a Lenovo, but an 80K9 laptop.

To be certain the reported issue is not related to corruption in the user profile, could you please reset your Libreoffice profile ( https://wiki.documentfoundation.org/UserProfile ) and re-test?

I have set the bug's status to 'NEEDINFO'. Please change it back to 'UNCONFIRMED' if the issue is still present
Comment 7 severoraz 2017-11-01 09:01:19 UTC
Ok, tested. The problem is still there.
Comment 8 Xisco Faulí 2018-01-08 10:58:57 UTC
Could you please create and attach a screencast showing the problem?
There are various free screencast software available for use, including Camstudio (Windows), Jing (Mac), Simple Screen Recorder (Linux) or screencast-o-matic.com (Web).

screencast of zooming action in LO Calc

The zoom depth depicted in the screencast is the result of scrolling a length of less than 2 cm in the touchpad. It is thus very hard to reach a specific zoom depth, since the zoom steps are very coarse.

I have the same problem, see bug Bug 123121.

Don't see how a screencast would help. Maybe a video of the user's fingers on the touchpad + the crazy fast scrolling.
