SUMMARY Once opening up Dolphin on one screen in a dual screen 4k setup it works flawlessly. Moving a Dolphin window from one display to another breaks Dolphin, one cannot click or select anything anymore in the active view (breaks bookmarks etc.). Reproducible on latest Arch stable release. STEPS TO REPRODUCE 1. 4k dual setup (on xorg, NOT wayland): open Dolphin 2. Make sure that file selection works 3. Move window to other screen 4. Dolphin will not work anymore unless restarted (no file selection anymore, no bookmarks, everything is basically rendered useless) OBSERVED RESULT Dolphin stops being usable, restart of application required EXPECTED RESULT Dolphin should continue to operate as expected/intended. SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
seems gone, closing my bug report.
