> Started kmail on wayland-plasma with active preview pane. The preview stays > black at the beginning. When e.g. hovering with the mouse over the preview, Do you see a black rectangle like in the image I've attached? That is https://bugs.kde.org/show_bug.cgi?id=397825 . If not, try to get a screenshot with Spectacle (it might not work unless you choose Full Screen or Current Screen). > clicking on a different email or changing the folder the whole kmail > software stops reacting and the title bar shows an unresponsive > notification. No crash notification. Have you tried using gdb to see what's going on? Do you get any output if you run KMail from a terminal emulator?
