Reproducibility: 100% on every distro running gnome 40 and 41. Ubuntu Version: 20.10. Package: gnome-shell 40.5-1ubuntu2 500 Background: Under Wayland, there are multi touch gestures implemented for the touchscreen and for the touchpad. 3 fingers up for activities overview and again for applications swiping left and right will switch desktops, in and out of the activities screen. Using the touchpad everything is fine and the system works as expected. as long as there are no programs running, using three fingers on the screen will go into the overview and move between desktopsas expected. The Bug: As soon as you enter overview with applications running and you swipe an app with more than 1 finger the entire shell will freeze and you cannot move to the other TTYs using the ctrl+alt+f#. Only the mouse still moves and there is an app preview stuck (see attached image). If you wait until the computer locks you can enter the lockscreen and the other TTYs. Expected Behaviour: System not hanging when swiping over an app window preview with more than 1 finger on the activities screen, The app should'nt be draggable with more than 1 finger. Swiping over the activities screen with 3 fingers should move between desktops overviews just like 3 fingers on a touchpad does and just like how it does when not doing so over an app. Edit: IMO, It might be a gnome bug, however as it is affecting the entire OS Canonical should patch it with a little hack/gnome addon that prevents dragging an app preview with more than 1 finger.
