Blender Version
Broken: version: 3.5.1, branch: Unknown, commit date: Unknown Unknown, hash:
UnknownWorked:
3.3 lts - latest version on steam that didn't recognize my touchpad as a touchpad (no wayland)before 3.3, but unknown, but probably since the start of touchpad support,Short description of error
panning with the touchpad doesn't move the camera in the same direction as it would with a mouse, despite rotating and zooming both being the same.
it seems that (on windows / macos) the natural scroll setting on a touchpad only affects the pan and zoom actions, and the natural scroll setting on a mouse only affects the zoom action (since panning is a drag action instead, but it's odd that orbit is the only one that doesn't change)
Exact steps for others to reproduce the error
pan / orbit / zoom the camera with a precision touchpad
compare with same same actions on a mouse
(see attached video)
Are you on Gnome?
If so, there seems to be a setting affecting this, called
Natural Scrolling:Could you check if this works for you?
i'm on KDE, the natural scroll setting just inverts all scrolling (except for the two-finger pinch), which means that while the panning matches what i'd expect, orbiting & zooming get inverted. maybe some way to like invert a trackpad/mouse-based keybind (so one could just invert the 3d view pan) would be nice? since i can somewhat see how the current mode could make sense
@ideasman42 : I recall a previous discussion about this, it seems users percieve this as being inverted, opinions?
Closing as this looks to be a known limitation in KDE.

Run Blender with the following command:
If the text
axis_relative_directionis not included in the output (when using a track-pad) this means the compositor is not aware of physical track-pad direction, once the compositor supports this, Blender should work as expected.in that case it's interesting that it also happens on macos
@Michael-309 please report this separately, reference any other reports you think it may be related to.
so just create a new issue saying it's the same bug as this, but it happens on linux, mac, and windows (now that i've fixed my driver issues and tested it there)? (tbf i probably should've included that in the original report)
@Michael-309
Re-opening, in this case, please update the report to note that it happens on Windows/macOS.
This means it's more likely to be a decision on how user interactions should work and less likely to be an error in the platform's event handling logic.
As Wayland only added support for physical track-pad direction very recently, I think it's best to investigate the problem on Windows/macOS before double-checking Wayland's behavior. Since those platforms have supported track-pads much longer.
by the way, i edited the issue the information (tested on more systems) a while ago, not sure if it gave a notification though
In addition to possible OS-specific issues, there are plenty of bugs in the way operators handle trackpad events.
The main patch is here #89906 (comment) some more in #82006.
You can find an explanation of how it's designed to work here: #102762 #89906 #86025 ...
@Michael-309 There are builds you can try and an explanation of how it should work: #111141 (comment)
You seem to have everything working correctly, as it should with the "natural scroll" option turned off.
You can invert the zoom direction in Blender settings.
There is a report #86025 about inverting the orbit, but it is a feature request actually.
@Michael-309 hi, on which platform you're observing this?
(Report description is complaining the problem on many OS)
On Windows, navigation direction is same for both mouse and touchpad. Well, there are some exceptional cases (which @jenkm has mentioned, example: #89906) :)
@PratikPB2123 all three (minus the notes on windows/macos, which i believe is actually the linux laptop's problem because of that wayland bug),
@jenkm the patch you linked doesn't seem to change anything on the linux machine, and unfortunately is too new of a blender to run on my windows/macos laptop.
i guess it is just me thinking the current controls feel wrong and it's intended
On Windows (at least) I can confirm inverted navigation direction:
Down motion scrolls upWe already have a few reports complaining about inverted directions so I think we can safely close this report.
Feel free to comment or reopen the report in case of misunderstanding.
I am using Blender 4.0.6, KDE 5.27.9 on Wayland, Linux 6.6.2
and facing same issue as @Michael-309, orbiting and panning are working differently on touchpad.
case 1: without natural scrolling
case 2: with natural scrolling
pinch zoom works normally in both cases.
I prefer to use natural scrolling in my system, and that reversed orbit is driving me nuts.
For now I am doing a temporary workaround of editing
view3d_navigate_view_rotate.ccto invert orbiting.But I would really like to have options in settings to individually "invert orbit" and "invert pan" in official builds.
