Created attachment 169308 [details] Bzip'ed mail causing 100% cpu usage on 1 core. SUMMARY A friend of mine sent me a mail because he needed help writing a shell script. Just displaying his mail in the message viewer part or message viewer window takes 1 cpu core (100% cpu usage on that core). Changing the view to another mail makes the cpu usage go back to normal. What I found strange is that even though I've often received mails from gmail (since he's at gmail), I've never faced such a behavior. I suspect it comes from how the mail is formatted. Maybe its size (12MB !) but not sure. STEPS TO REPRODUCE 1. Open the mail in kmail 2. Look at the CPU usage OBSERVED RESULT Usage of one of the CPU core is at 100% by kmail. EXPECTED RESULT CPU usage should not be at 100% when displaying a mail :) SOFTWARE/OS VERSIONS Operating System: Debian GNU/Linux 12 KDE Plasma Version: 5.27.10 KDE Frameworks Version: 5.115.0 Qt Version: 5.15.10 Kernel Version: 6.7.12-amd64 (64-bit) Graphics Platform: X11 Processors: 4 × Intel® Core™ i7-7567U CPU @ 3.50GHz Memory: 31.2 Gio of RAM Graphics Processor: Mesa Intel® Iris® Plus Graphics 650 Manufacturer: Intel Corporation Product Name: NUC7i7BNH System Version: J31153-308 ADDITIONAL INFORMATION
