Version: 4.4.10 (using KDE 4.6.2) OS: Linux Hello everyone, After i enabled HTML formating in Kmail composer replying to long messages has become a headache. Kmail hangs, interface is completely frozen, during which time CPU usage is high. After a period of time (depending on how long the message to which i reply is) the program recovers for a few seconds and i can type a few words then in hangs again and the cycle goes on. Reproducible: Always Steps to Reproduce: 1. Enable HTML formating in Kmail's composer. 2. Exchange several emails by replying (keep quoting the original messages). Do it until the email becomes several hundred lines long. 3. As the email grows longer the responsiveness of Kmail will decrease until it becomes unusable. Actual Results: Kmail becomes unusable - frozen interface for both composer and main KMail window. Expected Results: To let me type the message. Never happened when i was writing plain text messages
Please retry with Kontact 4.6.1
(In reply to comment #1) > Please retry with Kontact 4.6.1 I upgraded KDE to 4.6.5 but Kontact is still 4.4.10. Which version of KDE comes with Kontact 4.6.1?

I can confirm that this bug is still existent in kmail 15.12.1-1. It is really frustrating. If anyone needs some more info, please let me know.

Quoting Laurent Montel in #334469: Indeed I confirm it's QTextEdit which has this problem. => a bug in qt not in kdepim. === End quote -> If this is really still the case 10 years later, it might be time to open an issue with Qt...

Marking as confirmed as this has 8 duplicates including relatively recent ones (though none in Qt6 yet).
Created attachment 171975 [details] attachment-3800166-0.html Dear Louis, I'm a recipient of the status updates of this bug I once claimed. My question is: What are the next steps, do you mean an Qt issue is already opened now? It is so annoying and unacceptable that Kmail suffers from freezing email for more than decade. Many thanks for short reply!

Dear Bernhard, I was actually opening a report for another freeze and spotted the half a dozen duplicates of this one (that I've also been experiencing) so I decided to consolidate the information. I think the first step would be to reproduce in a Qt6-based KMail. Then, we should double-check the statement from Laurent Montel I pasted (Laurent is still one of the main devs but he checked this 10 years ago...) Depending on whether this is confirmed on the KMail side, a minimal repro should be written to open an issue with Qt, or KMail should be fixed.

Sorry for the email replies with quotations. I quickly confirmed the following in a Qt 6 build: Editing long messages is slow. I typed the word "test" many times, one on each line. I start feeling the performance at 100k words, and at 500k words it becomes unbearable (1s to type a single letter). KWrite is still super sleek at this level. I did the same test in a simple QTextEdit and got results similar to KMail's editor. It does seem to be a Qt bug.
Upstream bug: https://bugreports.qt.io/browse/QTBUG-17182 It was also commented on this report that QTextEdit was never meant to handle large inputs, so mitigation might be needed on the KMail side (many mail clients collapse answers by default or make them read-only, maybe something similar could be done...)
