Short description of error
"Toggle Window Fullscreen" on the new Fedora 34 (Wayland mode) makes mouse cursor disappear.
Exact steps for others to reproduce the error
Just select "Toggle Window Fullscreen" from the "Window" menu item at the top menu bar. Please do not start whining about the GPU no longer being supported, this is just about a disappearing mouse cursor after an upgrade from Fedora 33 (where the mouse cursor still works) to Fedora 34. Reverting from fullscreen to Blender in a window and the mouse cursor is shown again. With a hidden mouse cursor Blender does respond to moving the mouse and hovering it over buttons.

The problem is with Mutter, when following the following test fix, Blender can be toggled back and forth to fullscreen windows with a visible mouse cursor:

For completeness, here are the commands given in that Red Hat / fedora bug report and its comments:
Please note that this is a temporary fix, rebooting your system again will cause the mouse cursor to disappear again in fullscreen Blender.

Is this still the case on the current master? I merged HiDPI support (D11368) a while ago that also touched the cursor image and I cannot reproduce the issue that you described.
I just tried Blender 3.0.0 Alpha
5f5cf21a83
and the problem is still there, switching Blender to "Window Fullscreen" and the mouse cursor in the viewport disappears. The same happens in a webbrowser (Brave / Chrome) too, when watching a YouTube video and then going fullscreen there, again the mouse cursor disappears, making it hard to change settings like resolution of the video.I just tried logging out of Fedora 34, which by default uses Wayland these days, and logged back in using GNOME on Xorg, which makes Blender toggle "Window Fullscreen" without any problems, so it must be Wayland related...?
Well, if this also happens with other applications, then it is not Blender specific. Maybe this also happens only with newer GNOME versions or only with the AMD driver. I suggest you report that issue to https://gitlab.gnome.org/GNOME/mutter so it gets fixed in the Wayland compositor of GNOME Shell.
I take it that you are running the standard Blender with X11 on XWayland? if so, you could compile Blender with native Wayland support (https://wiki.blender.org/wiki/Building_Blender/Linux/Ubuntu).
In any case, I don't think there is anything that we can do in Blender to fix that issue. If this is not Blender-specific and can be fixed here, then please close this issue so we can keep track of issues with Blender itself that can be addressed by patches.
Changed status from 'Needs Triage' to: 'Resolved'
Closing this report, reporting it at GNOME and hoping this report does stay inside the system, for others who may run into the same situation...
@Memento Can you share a link to the issue report? I am curious about reproducing this.
