Description Alexandre Pereira 2022-11-30 17:04:55 UTC

SUMMARY
Switching virtual desktops using Ctrl+Alt+MouseWheel seems inverted in the direction of just using the mouse wheel on the desktop.
In my case, doing Ctrl+Alt+MouseWheel Up switches a virtual desktop down, and Ctrl+Alt+MouseWheel Down, switches a virtual desktop up. ( I have virtual desktops in a vertical layout )
The opposite happens when just using the mouse wheel and scrolling when the desktop is focused.

Using the mouse setting on the mouse kcm, of inverted scrolling, the opposite from above happens, and the behaviour of the two ways of switching virtual desktop are still different.


STEPS TO REPRODUCE
1. Add some virtual desktops
2. Switch between them using Ctrl+Alt+MouseWheel
3. 

OBSERVED RESULT
The Virtual Desktops switch in an inverted manner, like if it was a gesture movement, not a mouse wheel on a desktop.

EXPECTED RESULT
The Virtual Desktops to switch down when the mouse wheel is scrolled down, and up when scrolled up on the mouse wheel.

This one depends on another patch. Here's a correct one for Plasma 5.27.9

Also affected by this bug : kwin 6.0.4 - Archlinux

It seems this shortcut is not widely used/known for this bug to go unnoticed this long.
