Title:
Opening new windows or menus (e.g. "File") in programs, switching
workspaces becomes slower and slower over time in Gnome
Status in gnome-shell package in Ubuntu:
Confirmed
Bug description:
During normal use, opening new windows, opening dropdown menus (e.g.
"File", "View" in any program) becomes increasingly slow in Gnome.
After reboot, all such events occur almost instantaneously, but during
normal use over several hours (including suspending the laptop by
closing the lid) such events become increasingly slow. After several
hours of use, opening a dropdown menu might require several seconds of
waiting, during which the UI is completely unresponsive and does not
update. Every time an event is called, the syslog (/var/log/syslog)
gets filled with messages like:

It appears that the system is stalling while these events are being
sent to syslog.
