A vertical touchpad gesture stutters if performed immediately after a workspace switch swipe.

Vertical touchpad gestures (e.g. swipe up for Overview) stutter or briefly mis-trigger a horizontal movement when performed immediately after a workspace-switch swipe.


STEPS TO REPRODUCE
1. Use Plasma Wayland with default touchpad gestures enabled.
2. Perform a horizontal workspace switch gesture (3/4-finger swipe left or right).
3. Immediately perform a vertical gesture (4-finger swipe up/down).

OBSERVED RESULT
The desktop stutters (tries to move right/left).

EXPECTED RESULT
The vertical gesture should be recognized cleanly with no horizontal movement or stutter.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Fedora 43
KDE Plasma Version: 6.5.4
KDE Frameworks Version: 6.21.0
Qt Version: 6.10.1

This issue doesn't occur in plasma 6.4.5

This should be fixed in Plasma 6.6 where a substantial improvement was made to the smoothness of opening this KWin effect.
