tdesktop does check QWheelEvent::inverted property and reacts accordingly. That's all it can do. If it doesn't work for you, you have a bug somewhere on system level.

@ilya-fedin apparently that spec just doesn't work under wayland? maybe just in kde?

why can't this be forced using a toggle?

Maybe? That doesn't mean other compositors can't implement the same.

hyprwm/Hyprland#7836 (comment)

I heard the inverted property is implemented for the Wayland QPA backend. The X11 QPA backend indeed doesn't have support for this. I think hyprland developer can see how to integate with Qt by looking at qtwayland source code.

The policy is to have as less settings as possible. That's really something that the system should provide via some API. And that's not a problem for 99% of the users (Linux is only 1% of tdesktop userbase).

This seem to look like wayland is pretty aware of natural scrolling?

Such a toggle would also be relevant for just 1% of users, wouldn't have to be visible otherwise
