Version: (using KDE KDE 3.2.92) Installed from: SuSE RPMs OS: Linux I have an IMAP account with several folders (maybe around 100). When KMail checks for new email, the folder panel (on the left) is redrawn quite often even when there is not a single new email. Therefore, the folder panel starts to "flash". This seams to be unnecessary.
Do you use the unread count behind the folder name a la "foo (123)" or the total and/or unread columns?
I use "foo (123)". When I enable the unread columns, the problems does not seem to occur. It seems to happen only if most folders are collapsed.
Aye. I recently fixed the flicker for the separate column case, but since the color of the numbers in paranthesis needs to be configurable, according to the solitary opinion of a certain maintainer, I can't fix that case without opening up the chest of the patient and going to work with a power drill, so I didn't. I encourage everyone annoyed by this flicker to vote for this bug, so that maybe Ingo will see the light one day. ;)
I fully agree with Ingo that the unread color should be configurable, and as a numbers-in-parenthesis user would be sad to see that changed. I'm interested in any info about what change introduced it and/or what is causing it. Don.
The flicker has been there since I started hacking/using KMail. It is caused by the two rendering passes in KFoldertree::paintCell() necessitated by the custom color. The only way to fix it I can see is to duplicate large portions of the inherited paintCell(),which I refrained from. If you want to see it more clearly, try running KMail over an ssh tunneled X or somesuch.
Can't reproduce any flickering when rechecking IMAP mailbox on KDE 4.9.3. Fixed?
Thank you for taking the time to file a bug report. KMail2 was released in 2011, and the entire code base went through significant changes. We are currently in the process of porting to Qt5 and KF5. It is unlikely that these bugs are still valid in KMail2. We welcome you to try out KMail 2 with the KDE 4.14 release and give your feedback.
