Issue with "smooth" scrolling

[GbGp]

Hi, I am using the xpra client under wayland and I am unable to scroll using the touchpad (two-fingers scrolling) or the trackpoint.
I can see that scrolling with any of the two generates GDK_SCROLL_SMOOTH events, but as far as I can see those are not handled in xpra. Any suggestion?

@GbGp you can try the commit above (trivial to apply) or wait for the 4.2 release.

Works-for-me on my laptop.

works perfectly, thanks!

The problem is that normal scrolling events now come up as "smooth scroll" events, with the direction reversed.
And I can't see an easy way to differentiate between real smooth scroll events and the ones synthesized from regular scroll wheels.

So 41ba5af inverts the Y direction.
The commit above also makes it possible to turn off smooth scrolling.

You can use --mousewheel=invert-y.
