Compiz spends 94% of its CPU time in glTexImage2D() from
nux::IOpenGLSurface::InitializeLevel() from ...
nux::GraphicsEngine::CreateTextureFromBackBuffer when the dash is open

Title:
painfully slow desktop
Status in “unity” package in Ubuntu:
Incomplete
Bug description:
I didn't have this problem in 12.04. The system boots fine but after some
time of opening and closing windows, the system becomes painfully slow. The
animation to close a window takes around 3 seconds, it starts when you click
the close button, but then the animation plays in like 2 fps. and skipping
frames (it happens too when you restore, minimize, etc).
The notification popups become very very slow too. It is almost impossible to
alt+tab also. In every move, compiz takes the whole core. Idle around 30%. But
it doesn't start like this.
