I'm getting the same error on GNOME 47 on Ubuntu 24.10 but it works fine on GNOME 48 on Ubuntu 25.04beta. Both using Wayland.

Gnome 47 and older probably don't support that function, best solution to this is to change

"this._tracker = global.backend.get_cursor_tracker(global.display);"
back to
"this._tracker = Meta.CursorTracker.get_for_display(global.display);"

and add "import Meta from 'gi://Meta';" before "import Clutter from 'gi://Clutter';" in cursor.js

Hey @cringifyq , just wanted to say thanks — your solution worked perfectly!

I went into ~/.local/share/gnome-shell/extensions/wiggle@mechtifs/cursor.js and made the changes you suggested. After restarting GNOME, the extension works great on my setup (GNOME 47.4 on Bazzite / Fedora Atomic).

Really appreciate the clear fix 🙌

[danielschwab]

I created a PR (#19) for the suggested solution.

@mechtifs can you please integrate the PR and release a new version so we all can use the extension again (without local fixes).

New version has been published in GNOME Extensions and the issue has been fixed.
