Version: (using KDE KDE 3.4.1) Installed from: SuSE RPMs OS: Linux I have used kmail for a long time, and often via an X connection (through DSL) to access my desktop mailer from anywhere. Not terribly efficient, but it worked. Somewhere between KDE 3.3.x and 3.4.1, kmail has started doing lots of redraws - e.g., immediately after startup, the message list is refreshed five times, line by line, without any user action. This takes a long time, and makes using kmail via X practically impossible, unlike in earlier versions. Similar redraws happen for the folders list, but not for the message body (which is "only" redrawn twice). I am reporting this because I hope that the unnecessary refreshes can somehow be tcacked doen and fixed, making the client faster for everyone. I do not see this behavior on the desktop itself, just via X - my guess is that the extra flickers just happen too fast on a local display. Ah yes, perhaps unrelated, lots of errors of this type have appeared: X Error: BadWindow (invalid Window parameter) 3 Major opcode: 25 Minor opcode: 0 Resource id: 0x57 Thanks! VB
I know this isn't an answer to your problem, but you should use NX instead of pure X if your connection isn't over a really fast line.
Do you still see a lot of repaints with KDE4? Almost all the flickerings are gone now.
Hi, I have no current kde4 system available to test at the moment, but will try to get back to it (and either confirm that the bug still exists, or close) when I get a more current version. Thanks for paying attention to this! best, VB On Jul 20, 2009, at 2:53 PM, Jaime Torres wrote: > https://bugs.kde.org/show_bug.cgi?id=108024 > > > > > > --- Comment #2 from Jaime Torres <jtamate gmail com> 2009-07-20 > 14:53:08 --- > Do you still see a lot of repaints with KDE4? > Almost all the flickerings are gone now. > > -- > Configure bugmail: https://bugs.kde.org/userprefs.cgi?tab=email > ------- You are receiving this mail because: ------- > You reported the bug.
Thanks for checking with a current kmail version.
This bug is still exists in KDE 4.3.3 (Gentoo). I deleted lots of e-mails (about 180-200 so not too many) from my IMAP box and it was incredible slow. It runs 15 minutes and did only approx the third of the job. I checked the traffic, and it was only 5-10 packet bursts then nothing for some seconds, and it repeated. I checked the CPU usage with htop and I saw one of my CPU cores (Phenom, 4 core) is eaten by X. I minimized the KMail window, the CPU usage drops to normal level, and the deletion is finished in a minute. I can do other tests or compile snapshot codes for testing if it's needed.
Another observation: This only happens if a background filter run is in progress. If no filtering is done, the delete/move operation is fast.
I think this can be closed as KMail2 obsoletes KMail. I can't experience this problem under KMail2.
