Bug#928662: Additional report

[hoxp18]

Dear maintainers,

Still org.gnome.Shell.desktop produces tons of logs
during AppArmor enforced apps usage.

I've re-checked BIOS clock, NTP sync; it did not help.

As I posted, time delta is almost 2 such as,

org.gnome.Shell.desktop[PID]: Window manager warning:
   last_user_time       (33984584) is greater than
   comparison timestamp (33984582).
   This most likely represents a buggy client sending
   inaccurate timestamps in messages such as _NET_ACTIVE_WINDOW.
   Trying to work around...

My tentative proposal:

How about check those time/timestamps a bit loosely?

pseudo-code:

     timedelta = last_user_time - comparison_timestamp
     if timedelta > 2:
         warn("Window manager... is greater than..")

Regards,
