Same bug. Normal cursor not change.
firefox flatpak 104.0.1

Fedora 36
Kernel: 5.19.6
DE: GNOME 42.4

Resizing works but it's hard to resize as you have to do it by feel :D. When you click in the right place the cursor changes to the right one for resizing the window.

Is there a chance that we will get the proper resize cursor back?

A bunch of cursor icons are reported as missing when running on GNOME/Wayland with MOZ_ENABLE_WAYLAND=1 set in the flatpak:

Gdk-Message: 14:19:46.522: Unable to load sb_h_double_arrow from the cursor theme
Gdk-Message: 14:19:46.705: Unable to load hand2 from the cursor theme
Gdk-Message: 14:19:46.745: Unable to load hand2 from the cursor theme
Gdk-Message: 14:19:46.789: Unable to load hand2 from the cursor theme
Gdk-Message: 14:19:46.827: Unable to load hand2 from the cursor theme
Gdk-Message: 14:19:47.321: Unable to load split_h from the cursor theme

Notably these are part not part of the Freedesktop runtime (22.08) which ships no cursor themes as far as I can tell. But bundling a particular cursor theme (say Adwaita, that provides these) with the flatpak in /app/share doesn't help either. My guess is maybe the path is hardcoded to /usr/share/, so using it with the GNOME runtime solves the issue: flatpak run --runtime=org.gnome.Platform//43 org.mozilla.firefox for me.

Setting the XCURSOR_PATH environment variable also seems to solve the issue for me. flatpak bind mounts cursor paths from host to /run/host to make them available in the sandbox:

flatpak run --env=XCURSOR_PATH=/usr/share/icons/:/run/host/share/icons:/run/host/user-share/icons org.mozilla.firefox

Oddly, that shouldn't be needed as it is already set here in the freedesktop runtime https://gitlab.com/freedesktop-sdk/freedesktop-sdk/-/blob/bca76217515b3c3cbf1f14a2dde050f277bf5942/elements/components/xorg-lib-xcursor.bst#L16

@nanonyme in #flatpak mentioned that this could be related to https://gitlab.com/freedesktop-sdk/freedesktop-sdk/-/merge_requests/9702

I have tried running Firefox with

flatpak run --env=XCURSOR_PATH=/usr/share/icons/:/run/host/share/icons:/run/host/user-share/icons org.mozilla.firefox

but this didn't help me. I am on X11 here.
