Public bug reported: I'm a relatively heavy desktop user, having multiple browsers running at any given time, lots of terminal windows, etc. However, my browsers don't use a lot of CPU as most of the tabs are suspended at any given moment.
On a regular basis, over time, my desktop becomes less and less usable. It starts with becoming noticeably slower, laggy, and eventually absolutely requiring a reboot since it becomes totally unusable. At the same time my my system load is low, and remains low, while gnome- shell appears only to take more and more CPU. I often see it using 30, 50, 90, and sometimes 100% CPU, while the rest is idle. It reaches the point where terminals don't easily The only "fix" is rebooting, or restarting X. I must admit that I've been seeing this on my laptop for years now, and there is no improvement in sight even though I upgrade Ubuntu to the next version every time an update is out.
