Description Pranav Karande 2023-05-17 12:16:32 UTC

The one-to-one animation when switching virtual desktops using 4-finger or 3-finger swipe is linked to the slide desktop effect. I want to switch to a virtual desktops instantly without animation when I use keyboard shortcuts or by clicking on them in the pager but still want the smooth one-to-one animation when using trackpad gesture.

STEPS TO REPRODUCE
1. Disable Slide desktop effect
2. switch between virtual desktops using 3-finger or 4-finger swipe

OBSERVED RESULT
Switches to new desktop at the end of the swipe without any animation

EXPECTED RESULT
The smooth one-to-one animation

The slide effect is the thing that provides the 1:1 animation for touchpads, so I'm afraid there is no way to disable the effect but still have such a feature.

What would be possible is to do one of the following:
- add a setting to disable the effect's animations when switching using something other than a touchpad gesture
- automatically don't use the effect for switching when using something other than a touchpad gesture

But I think these are very niche and would not have broad appeal, requiring a lot of code for little benefit. So I don't think we'll be doing it, sorry.
