Public bug reported:

After resuming from screen saver ccometen4 from repositories left
running over-night (and monitor sleep after 1/2 hr), Xorg consumes 100%
of a single CPU core (amd64 dual-core).

Happens every morning... but not when the screen saver is used for only
short periods.

I suspect it's not a direct result of the screen saver, but a bug that
appears in Xorg only after running several hours, or that ccometen 4
exercises Xorg pretty hard.

Running nVidia stable 185.18.14
