set_cursor_icon does not work

[antoniocorbi]

Describe the bug
I simply want to change the mouse cursor whenever it is on my window. For that I make a call like this in my update function: ctx.set_cursor_icon(egui::CursorIcon::Crosshair); but the mouse shape does not change.

To Reproduce
Call set_cursor_icon as docs say.

Expected behavior
The mouse cursor changes to the one selected

Desktop (please complete the following information):

• OS: NixOS 24.11, gnome-47 + Wayland
• Version: egui/eframe 0.31.1

Update:

Hi, I just wanted to add that I've tried my app that uses set_cursor_icon under sway and the mouse cursor changes as expected.

Same issue. I'm using egui in a web app (WebAssembly) running in browsers.

Does the cursor test on egui.rs and when running the demo app locally work correctly for you?

For me on macos it works correctly (both locally and in the browser)

My only problem with this is under gnome-47 + wayland.
The same application works ok when executed using sway (wlroots) as window manager.
