Hello.

i use fluxbox and usually fluxbox is very fast. but yeserday and actually every third day a very strange problem appears: my fluxbox and the general visual system becomes very very slow:
usually i get 4000 frames per 5 seconds with glxgears, but in this strange period i just get 180 frames per 5 seconds!
thats not normal!

in gnome this phenomenon also appears!
