Created attachment 163197 [details] In that screenshot, you can see the mailbox selector remained in the dark colorscheme, while the email content changed to the dark colorscheme. Description: SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** Part of KMail's UI seems to 'get stuck' on the last colorscheme it updated to, and not update in colorscheme uniformly. STEPS TO REPRODUCE 1. Set colorscheme to breeze-light 2. Open KMail 3. Set colorscheme to breeze-dark OBSERVED RESULT Part of the UI (the mailbox selector and the message list) does not update it's colorscheme EXPECTED RESULT The whole UI's colorscheme will update correctly SOFTWARE/OS VERSIONS OS: Arch Linux KDE Plasma Version: 5.27.9 KDE Frameworks Version: 5.112.0 Qt Version: 5.15.11 Graphics Platform: X11 ADDITIONAL INFORMATION All other KDE apps I've tried, such as Dolphin and Kate seem to handle changing colorschemes while it's running gracefully, both minimized and visible. So It appears to be unique to KMail.
It seems ok in last version. Please reopen it if you still have bug in last version
