On Fedora, glfw isn’t built with wayland support. Building it from git with wayland enabled, I see the opposite problem: the cursor is tiny, except for the titlebar provided by libdecor which has the correct size.
I see similar behavior in weston, so this is probably a glfw bug:

Wayland
libdecor's decorations seem to properly keep cursor size as with the rest of com… positor. The glfw viewport however seems to pick up cursor size from XCURSOR_SIZE environment variable. However, when this environment variable is missing it seems to set it to an odd size instead of directly requesting size from the compositor.
I'm using glfw-wayland 3.3.9 from Arch Linux repos, GNOME Wayland session.
Video demonstration of the issue:
[Screencast from 2023-12-18 21-46-03.webm](https://github.com/glfw/glfw/assets/68742864/ee5ce45a-46cc-4a9a-a334-2d9ffd844880)
#1352 mentions that this variable is set by the compositor, however, this is false (or at least not the case anymore). Instead, wayland compositors rely on a completely different way to obtain cursor size and theme (in case of GNOME, it's saved in a dconf property)
The primary use of XCURSOR_THEME and XCURSOR_SIZE is in Xorg.
