Dragging a Box On Konqueror Or Desktop Lags

Hi!

I've been having this weird bug. When I try to drag a box on desktop or konqueror, it lags. The bigger the box, the more lag it is. I'm sure it's not due to hardware as glxgears give me ard 10 000 fps. I've tried using both YAST's drivers and nvidia's legacy drivers to no avail. Anyone has any idea on how to fix this. I heard some ppl say it's some problem with the rubber band patch... No idea what it means.

Thx in advance!

I found out a workaround on this problem by enabling translucency setting in KDE. This is what I did to my xorg.conf.

Does KDE support transparency and other visual effects provided by the new composite extension to X.org?

Yes! An exciting new feature for KDE 3.4 is support for the new X composite extension. This allows for effects such as translucency and drop shadows for all windows, easily configurable through KWin's configuration dialog. This requires you to be using X.org version 6.8.0 or newer and have:

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

In your xorg.conf. If you have an nvidia graphics card and use the nvidia driver you can improve the performance of these effects by also adding the RenderAccel option to the Device section for your graphics card:

Section "Device"
Identifier "nvidia-fx5200"
Driver "nvidia"
Option "RenderAccel" "true"
Option "AllowGLXWithComposite" "true"

Once you have configured X.org correctly, transparency and other effects can be enabled through the Desktop->Window Behavior KDE Control Center module, under the Translucency tab.

It was purely accidental that the option to use graphic card's power to help animate the desktop also fixed the dragging problem. It now works as it should be. However, I still feel that this bug should be fixed. Not everyone has a good graphic card..

Hope this helps...

Please consider the following:

Source code

 
1
2
3
4

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

This also improves the composite speed.

Composite however, is an experimental new technology. The lag in dragging the windows is normal and likely caused by the window shadow settings you've enabled with composite. This is something that will eventually disappear when KDE gets full support for the new composite extension.

For now, you use it to impress for friends, but disable it again to make your desktop responsive again. ;-) (either by removing the extensions section from your xorg.conf, or disable the transparency/shadow settings)
