application grid: right-click on an app icon, plus left-click on an empty space trigger a false scroll event
I have noticed right clicking on an app icon, and then left-clicking on the empty space at the end of the application grid can trigger a bogus scroll event that provokes a visual jump:
Can reproduce in:
- Debian sid (gnome-shell 3.34.1+git20191024-1 / mutter 3.34.1+git20191022-1)
- gnome-shell master / aa9031d8
- mutter master / mutter@e84dbd7f
