Lag in KDE (kdemod)

When I drag a selection box on the desktop to select files, X goes nuts and max at 100% cpu usage. It seems like the bigger the selection box gets, the more cpu it uses. It doesn't matter if I actually select any files or not. I have a completely new installation of kdemod and I've tried reinstalling it (including Arch), but no difference. I had no similar problems when I used GNOME.

When I make a selection box inside Konqueror, this doesn't happen.

Any ideas?

1. Please dont open new threads here but use the existing one if you have problems with KDEmod

2. You need to have the render and composite extensions enabled in your xorg.xonf. I dont know what graphics card do you have, but on my nvidia it looks like this:

device section:

Section "Device"
        Identifier  "Card0"
        Driver      "nvidia"
        VendorName  "nVidia Corporation"
        BoardName   "GeForce 7600GT"
        BusID       "PCI:2:0:0"
        Option      "NoLogo" "true"
        Option      "RenderAccel" "true"
        Option      "AllowGLXWithComposite" "true"
        Option      "AddARGBGLXVisuals"
        Option      "DisableGLXRootClipping"  "True"
        Option      "TripleBuffer" "True"
EndSection

extensions section:

Section "Extensions"
        Option "Composite" "Enable"
        Option "RENDER" "Enable"
EndSection

if you dont have a capable card, consider to disable the selection rubberband in kcontrols effects tab.

Re: Lag in KDE (kdemod)

funkyou: Disabling the rubberband effect did it. Thanks.

I doubted this problem was kdemod specific, I just included it incase it was useful to know. Should I still post in the kdemod thread, regardless if the problem is kdemod specific or not? It seems like searching for future kde problems will be hard if it's all located in one thread.
