Version: svn snapshot from 3.5 branch (using KDE Devel) Installed from: Compiled sources Compiler: gcc 4.1.0 OS: Linux I have a mailbox with 10000+ mails, when I use the search line to search for some keywords, kmail become very slow, either scrolling the result or rightclick on a mail. Even switching to another window and then switch back will make it hang for about 2s on my athlon-xp 2500+.
confirm this one at Mandriva Cooker, KDE 3.5.5, KMail 1.9.5 Not only is the search a bit slow, even worse - it seems, that the search is performed at every UI refresh, i.e.: 0) launch top 1) perform a quick search on a folder with 40k+ messages and wait for CPU to get back to 0 2) minimize and maximize KMail (or move the scrollbar or whatever) 3) watch it eating your CPU again the only solution is to use the full search
I spent some time to debug the problem, and I found that the bad guy is the alternative background of KListView, after comment out the code in klistview.cpp, the slowness went away.

Marking as a dupe of bug 138912, most probably it describes the general cause for this problem. *** This bug has been marked as a duplicate of 138912 ***
