Bug description

Scroll direction is different on Mac client between trackpad and mouse - Trackpad can be used to scroll normally in client's list of synced files. If a mouse is connected to the Mac M1 or M2, the behavior in this list is somewhat chaotic. The scrolling direction changes and entries jump.

Steps to reproduce

Click on the Nextcloud Client in the Mac menu bar with a mouse. Scroll with the wheel of the mouse.

Expected behavior

the same function of the mouse as the trackpad

Hi @ChristophSchl I cannot reproduce with a mouse on my M1 Macbook Air -- does your mouse have any special drivers or sfotware installed? Is there anything special about its scrolling? Does this happen as soon as you launch the client, or after a while of having it open? Thanks!

[ChristophSchl]

The scrolling direction is reversed to the general system. About the control field "natural scrolling" also reverses.
The mouse I am testing has a scroll wheel without a special driver.

I've recorded a short clip to better illustrate the issue. As you can see at the issue is only present when "natural scaling" and inside the task bar. Visible at timecode 0:05. Interestingly, the proper nc settings window doesn't show the same behavior.

I'm using a regular old school wired USB Mouse with a scroll wheel. For each section of the video I am moving my finger towards me on the wheel and then away for me.
Halfway through the video I demonstrate that the issue is not present when changing the OS scroll to "regular".

Recorded using version 3.8.0

same in 3.8.1

And what is the behavior of the Trackpad/Mouse scrolling direction when using the Finder?

Isn't it the same different behavior?
In my case I´m using a Logitech Mouse connected via Unify Dongle to the my Macbook Air M2 and I´m using the "natural scrolling" in the Trackpad settings of the OS.

Either you set the "natural scrolling" for Mouse or Trackpad inside the OS settings, both will be inherit the same setting from each other.

But I have resolved this by setting the Mouse scroll options with the Logitech Driver to "Normal" that overrides the OS settings when using this Mouse.

However, I think this sounds like an OS issue that Mouse and Trackpad are not configurable independent on each other.

No - My problem is that in the view with the synchronised files with a mouse, the scrolling direction of the Nextcloud client is interpreted exactly the other way round. All Mac applications push the content upwards when I use "Natural scroll direction". Only not in the Nextcloud window of the file sync.

In this window, scrolling with a mouse behaves incorrectly:
