Description LuRan 2006-12-17 13:16:33 UTC 
Version:           svn snapshot from 3.5 branch (using KDE Devel)
Installed from:    Compiled sources
Compiler:          gcc 4.1.1 with gentoo patches
OS:                Linux

The alternative color feature slow down the painting of the search result considerably, when there is a large 'gap' in the search results. For example, when the results of KListViewSearchLine contain the first 10 items, an the next is the 20000th item. The cpu will go crasy when the 20000 item should be painted. And there seems to be no cache mechanism, any refresh will cause a recalculation of the color.

This should be fixed in Qt4/KDE4 I believe.

does it mean this will not get fixed in KDE 3.5.x ?
