This is still an hard issue with up to date trusty, i'm only able to write this with running:
while true; do sleep 5 && kill -s 1 $(pgrep unity-panel-ser); done That's keep the system alive under "heavy load" from repeated Thunderbird messages and probably "indicator-notifications". dpkg -l | egrep ^ii | egrep -o indicator-\\S* indicator-appmenu indicator-bluetooth indicator-cpufreq indicator-datetime indicator-keyboard indicator-messages indicator-notifications indicator-power indicator-printers indicator-session indicator-sound Nice to watch the "balloning" ;) top -p $(pgrep unity-panel-ser) -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

Using shortcuts is enough and faster to reproduce this bug (I've always used Ctrl+A and Ctrl+Shift+A). Memory usage of unity- panel-service increases steadily and it uses a lot of CPU shortly after activating the menu items in a short time. Regression potential: check that the menus are stable/working as they should --------- Just going about my business on Ubuntu Raring amd64 on an x230 and I heard the fan kick into action. top showed me that unity-panel-service was consuming all the free cycles on one of my CPUs. I killed it before my machine overheated, so I didn't attach a debugger to see why it was totally pegging out a CPU. I'm not sure if this adds any context, but I was using a LibreOffice spreadsheet and I could not insert a table because the menu had lost it's mind, and then I observed the overly loaded CPU a very short while after that.
