Bug ID: 373368 Summary: Opening new message very slow and freezes KMail for several second each Product: kmail2 Version: Git (master) Platform: openSUSE RPMs OS: Linux Status: UNCONFIRMED Severity: normal Priority: NOR Component: message list Assignee: kdepim-b...@kde.org Reporter: renda.kr...@gmail.com Target Milestone: --- KMail 5.3.3 (QtWebEngine), OpenSUSE Tumbleweed, Linux (x86_64) release 4.8.12-1-default: Kmail is very slow when navigating between messages in the message list. I have two accounts - an IMAP account (Activated Download all messages for offline use) and a Local Folders account. To be sure this is no migration problem from KDE 4 I stopped KMail and Akonadi and removed the following folders and files: ~/.local/share/akonadi ~/.config/akonadi ~/.kde4/share/config/akonadi* After that I restarted Akonadi and resynchronized the account again. Thus, this should be a clean state. When having synchronized all messages after the above cleanup action the problem reoccurs again: I click on several messages in the message list, marking a new message in the message list freezes KMail for several seconds before the new message is shown in the message window. This behavior happened from my point of view since the QtWebEngine has been introduced as message viewer. Because I've read about multi-threading problems of Nouveau, I tried also the native NVidia driver, no change so far. -- You are receiving this mail because: You are watching all bug changes.
