high cpu usage when moving application windows
Hello all,
I have two machines with arch installed:
- an eeepc 701 surf/intel gpu(xorg driver) with xfce
- an amd 3800+ X2/nvidia 8860 gt(proprietary driver) with kdemod3(also checked with xfce4)/arch amd64 installed.
I noticed that when i move a window of an application(for example konsole, etc..) too fast i get high cpu usage(30-40 %), when checking with htop.
Is it normal that the X server uses the cpu so much when moving a window??
EDIT: up to now i tested it in a friends windows machine, and it happens exactly the same, so i guess is normal. It seems i need to be informed better about how X works :-)

Re: high cpu usage when moving application windows
today i switced back my desktop system to debian unstable and tried to see what the difference is concerning this problem.
I found out that in kde3 the solution to the "problem" is debians kde default configuration about window behaviour.
Especially the one mentioned below :
In debian this is not ticked and this has as a result zero cpu usage when windows are moved.
