While using KDE Plasma 5.11 on Wayland (starting from console as startplasmacompositor) I found that typing in Krunner search string is broken: it shows only one symbol, like typing "chromium" shows the first letter 'c', but then changes it to 'h' and 'r'. 'Enter' key does not run selected application from the list anymore. Additional info: Arch x86_64 GNU/Linux plasma-desktop 5.11.0-1 krunner 5.38.0-1 wayland 1.14.0-1 Krunner in Plasma on X works fine as usual. Steps to reproduce: Start Plasma 5.11 on Wayland, press Alt+F2, start typing and try to run selected application pressing Enter.
