Version: (using KDE 4.3.1) Installed from: Ubuntu Packages When I write a mail in the composer it takes ages before the characters appear, like half a second per character. I type a few words and then wait and watch the characters appearing one by one. This makes the composer basically unusable (except for very short mails). I tried disabling automatic spellchecking, but that did not help.
This bug is related to bug 183389 and bug 193136. Are you using a remote display or have wordwraping disabled?
No, kmail runs locally and wordwrapping is enabled. (Disabling it, doesn't help either.)
Probably this bug is a duplicate of bug 119281.
Yes, this might be. One suggestion there is suspending composite, that helps for me too. OTOH this report is from 3.x times and thus might handle separate issues with the same symptom?
