Public bug reported:
Binary package hint: gnome-screensaver
Symptom:
The screensaver module IFS does (to my information) not use 3D
acceleration, yet on my old 500MHz machine it ran faster than today on
my 2GHz machine. I see that new features (changing colors) were added,
but that can not account for a >80% CPU usage in window mode (rather
small window).
Something has gone wrong, I think.
More information:
I did an strace, but do not know if this is normal as I never had the
incentive to do one before.
