Description Robert Mader 2021-06-21 03:22:05 UTC 
SUMMARY

GTK3/4 as well as Mutter and wlroots (oddly not Weston) implement the zwp_pointer_gestures_v1 protocol to allow pinch and zoom gestures on touchpads. It is used in apps such as Firefox, Gnome Web and evince and allows to make the touchpad experience match closer that of other OSes. It would be great to have it supported in Kwin as well.

Comment 2 Robert Mader 2021-06-21 03:51:04 UTC 
P.S. as little extra motivation: one of the main Firefox Webrender devs runs KDE and would love to debug pinch zoom on his main device :) So implementing would make some people very happy.

Urgh, sorry, it's already supported - just something with GTK is broken, on either side.

kwin implements the pointer-gestures protocol. It seems like a GDK bug.
