I updated my test distro to Fedora 34. I was already running a beta version of the shell, and the gestures were fine. After upgrading from Fedora 33 to the 34 prerelease (and going from kernel 5.10 to 5.11), the sideways gestures for switching dekstops still work fine but the up/down gestures for going into the overview have stopped working. I’m not sure how I could go about fixing this (or filing a bug report). Any help or thoughts are appreciated!
