Public bug reported: 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:
