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: [email protected]
Reporter: [email protected]
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.
