Smooth scrolling in zathura (on X11) acts funny:

- vertical scrolling (two fingers moving left/right on a touchpad)
  isn't smooth, page jumps by several pixels on every little finger
  movement

- horizontal scrolling behaves the same

- diagonal scrolling is perfectly smooth, page scrolls smoothly

Similar behaviour can be observed when zooming - two finger scroll while
holding Ctrl:

- scrolling vertically isn't smooth, zoom jumps by several levels

- scrolling diagonally results in smooth zoom adjustments

This definitely worked before, so I tested a few older versions from
snapshot.debian.org:

There were some fixes upstream between 2026.07.18 and 2026.10.4 but some
of that code is in libgirara and that's not yet updated in Debian.

Control: tags -1 fixed-upstream

This should be fixed by
https://github.com/pwmt/zathura/commit/e3d1fd46546e0974908ce93a879d36bda96f263c.
I would appreciate if you could test the patch.

Note that girara-gtk != libgirara. All changes in girara-gtk are part of
zathura.

Cheers

Hi Sebastian,

Yeah, works fine now indeed. Thanks :-)

Oh, I see. Good thing you mentioned this, made it easier to test the patch.

Best,
T.
