Title:
High CPU usage and lag
Status in Ubuntu:
Incomplete
Bug description:
From time to time, the desktop animations get very laggy, both in Unity and
in Gnome Shell. When this happens, the CPU usage of xorg is 20-25% on my quad
core CPU, according to top, so I guess one of my cores is maxed out by xorg.
The slowness is not constant. Instead it comes and goes.
For example
* It can take up to 1-2 seconds to switch between lenses in the dash in Unity
* Window movement is sometimes so slow that the window manager doesn't redraw
the window until I stop moving it, causing the window to disappear from the
window's start position and appear directly in its end position.
