Description ignazio.martinoli 2021-07-06 05:49:00 UTC 
SUMMARY
I was used to open new instances and scroll through windows in the dock via the mouse wheel. Since the last update the functionality is extremely broken. New instances doesn't open anymore with the wheel and scrolling between instances (i.e. LibreOffice documents) only work if you are fast doing it before a couple of seconds since the dock shows up.
I miss this functionality so much I had to downgrade the version. If you need any other info on the system to track this issue down I am willing to help (contact me on ignazio.martinoli@gmail.com).
I love Latte Dock and really appreciate your work.

Comment 1 Michail Vourlakos 2021-07-06 07:41:07 UTC 
Have you enabled in Tasks advance options the desired scrolling behavior?
Comment 2 ignazio.martinoli 2021-07-08 22:18:04 UTC 
Yes, I did it. In Actions, for the Wheel I selected "Cycle Through Tasks". Unfortunatly it didn't worked.

Comment 6 Michail Vourlakos 2021-07-10 05:20:09 UTC 
In your layout as set conflicted properties:

just set,
Tasks(advanced) -> Scrolling -> Manual -> Only Horizontal Scrolling

having both Horizontals and Vertical Scrolling breaks the wheel behavior you are interested in.

calculate scrolling length in (int) values

--calculations for tasks length exceed must be done
always in same arthmetic world either int or float for
all values. It is chosen the int case because latte
is providing applets length in int values

THANK YOU VERY MUCH! It was annoying me so much! I didn't figured out it was that. Thank you so much. It's solved now
