Missing cursor for tablet in Wayland session in git master

Affected version

  • Fedora 33
  • mutter from git master, tip @ commit 698fe3f1
  • Wayland

Bug summary

In Wayland, both the regular pointing device and the tablet used to have a separate cursor, one for each.

Using mutter from git master, there is no cursor for the tablet anymore.

Input events from the tablet still occur, yet without a cursor to show where.

Steps to reproduce

  1. Plug an input tablet
  2. Log in gnome-shell from current git

What happened

No cursor is shown for the tablet

What did you expect to happen

A separate cursor shows for the tablet.

Relevant logs, screenshots, screencasts etc.

Not much, only thing remotely relevant in the logs is:

But that's not really relevant for the case I reckon.
