I haven't played the new snapshot, and dunno if it still applies to it - I'll do that today tho.
When walking forwards (or pressing any key on the keyboard for that matter), laptop touchpads don't work on linux (gnome, popOS 21 and Fedora workstation 8). On other programs, gnome hides the cursor when typing. This issue doesn't affect normal mice.
Does MC-132460 describe your issue? It was also experienced in Linux.
