Public bug reported:
After resume from suspend. Gnome shell is lagging and takes 100% of one
of the cpus
I see the following in the logs
aj 16 10:33:12 graf sudo[745687]: pam_unix(sudo:session): session closed for
user root
maj 16 10:33:15 graf gnome-shell[200033]: Window manager warning:
last_user_time (394951544) is greater than comparison timestamp (394951533).
This most likely represents a buggy client sending inaccurate timestamps in
messages such as _NET_ACTIVE_WINDOW. Trying to work around...
maj 16 10:33:15 graf gnome-shell[200033]: Window manager warning: 0xa0000e
appears to be one of the offending windows with a timestamp of 394951544.
Working around...
