Since updating to KMail 5.15.1, upon start the UI shows no folders or messages.
STEPS TO REPRODUCE
1. Open KMail
2. UI is blank with no messages or folders available to navigate through
No content, either main email account, folders or messages shown in main interface. See https://i.imgur.com/qJh3SrH.png
Regular usage of KMail, including checking, viewing and actioning messages and navigating between account folders.
Linux/KDE Plasma: Manjaro-ARM KDE edition (Kernel ver 5.8.3-2-MANJARO-ARM)
(available in About System)
KDE Plasma Version: 5.19.5
KDE Frameworks Version: 5.73.0
Qt Version: 5.15.0
Running on up-to-date Pinebook Pro. Kmail config shows account info and previous setup (connected account password etc. still showing).
Issue appears sporadically after aprox. 5-6 launches of KMail and I assume it's a in-app render or display issue as it causes a complete crash of KMail after closing and restarting one time further,
