GNOME Shell 3.32.2 I've disabled the screen lock. I have set the screen to turn off after 5 minutes of inactivity. After the screen is turned off for inactivity, when I resume the session sometimes the mouse pointer disappears. Journalctl shows the following (I don't know if it's related): .... sep 19 18:48:03 Fedora-PC org.gnome.Shell.desktop[1595]: Window manager warning: W277 appears to be one of the offending windows with a timestamp of 99099973.

This most likely represents a buggy client sending inaccurate timestamps in messages such as _NET_ACTIVE_WINDOW.

What's your kernel version? Are you using the X11 or Wayland session? Does the mouse cursor disappear everywhere or just on the panel, background, overview etc? Does it return when you click on a window while holding the Super key (triggering a window move)?
Kernel version 5.2.15-200.fc30.x86_64 Wayland session The mouse pointer disapears in desktop (top bar, over background, gnome-shell menus...) but on the rest of the windows (Firefox, Gedit, Nautilus...) it still appears. Today it has happened to me twice while I was using various applications and it has worked properly again after minimizing/maximizing some windows.
Then I'm going to assume it's a duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=1738614. Current known work-around is to either upgrade kernel version 5.3 or downgrade to 5.1. *** This bug has been marked as a duplicate of bug 1738614 ***
