Did the tumbleweed upgrade to Gnome 40; currently running snapshot 20210416.

The newly introduced three finger up/down gestures are a bit wobbly.

It looks like I cannot produce enough "momentum" on the touchpad to move the
screen up for Activities and Applications (second three finger upwards
movement).

You can clearly see that the screen starts to move up a bit, but my fingers
reach the end of the touchpad before it fully moves to Activities/Applications.

If the mouse pointer is over firefox, weird things happen in firefox, sometimes
even the current tab is getting closed.

The most successful way with the three finger gestures is to move the pointer
out of any window and then do the three finger up swipe.

Once in the Activities view, it works a bit better if I have the cursor in the
greyish area.

Laptop is a Fujitsu S936.
