Does this mean we will no longer have the cursor changing when we hover on certain flatpak apps?
Gnome
The GNOME Project is a free and open source desktop and computing platform for open platforms like Linux that strives to be an easy and elegant way to use your computer. GNOME software is developed openly and ethically by both individual contributors and corporate partners, and is distributed under the GNU General Public License.
No, apps are free to use client side cursor decorations if they want to. Games typically do for their custom cursors. Gnome may want to do this, I don’t know.
Also, this protocol is currently only supported in GTK4. Wayland clients using GTK3 don’t have access to it. Chromium uses GTK3 but they added support for it outside of GTK. I don’t think Firefox supports it.
The giant cursor will keep tormenting me for the foreseeable future.
