I can confirm that Sublime Text 3 is a good candidate to notice this problem. Just accessing the global menu can dramatically increases CPU usage of unity-panel-service. Also, when Sublime Text is just started, accessing the menu for the first time will freeze the system for 1-2 seconds, and has individual items in the menu far apart horizontally. Maybe this graphical glitch can be a hint.

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.
