Bug ID: 425433 Summary: HTML Preview is slow (for some messages) Product: kmail2 Version: 5.15.0 Platform: Archlinux Packages OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: general Assignee: kdepim-bugs@kde.org Reporter: trilader+kdeb...@gmail.com Target Milestone: --- SUMMARY For some messages rendering the HTML preview is slow. After selecting the message it takes about 2.2 seconds (measured with stopwatch) before the message content is visible. If switching between messages the old message content is displayed while the message list already shows the new message as selected. For some messages it's faster but still takes around a second. The same message in Thunderbird load with no noticeable delay. STEPS TO REPRODUCE 1. Open/switch to a message from a sender which is set to display as HTML by default 2. Wait.. 3. See that it took some time to display it. OBSERVED RESULT Rendering the HTML message is slow. EXPECTED RESULT It should be fast :-) SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: 5.19.4 KDE Frameworks Version: 5.73.0 Qt Version: 5.15.0 ADDITIONAL INFORMATION I can supply messages to test with. -- You are receiving this mail because: You are the assignee for the bug.
