Bug 122735

Version:            (using KDE KDE 3.5.1)
Installed from:    SuSE RPMs
OS:                Linux

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. This hadn't happened to me last time when I use other distros. Not sure if this is distro-specific.

Thx in advance!

Workaround I discovered

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...
