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 *** STEPS TO REPRODUCE 1. Connect external display to NVidia driven port on Intel/Nvidia hybrid laptop 2. Move mouse from external display and primary display OBSERVED RESULT with inconsistent results, the image of the mouse cursor will remain toward the edge of the exited display while an active cursor will continue on the other displays. This "ghost" image cursor will remain until the active cursor re-enters the view of the external display. EXPECTED RESULT Mouse cursor flows from one display to the next, disappearing completely from the frame of the exited display SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE Neon (available in About System) KDE Plasma Version: 5.27.8 - Wayland Session KDE Frameworks Version: 5.110.0 Qt Version: 5.15.10 ADDITIONAL INFORMATION * display connected to NVidia driven port on an intel/nvidia hybrid laptop * reddit user Zamundaa is aware and wanted me to report it so they could look into possibly backporting a fix from 6 back to 5.27 * Original post: https://www.reddit.com/r/kde/comments/16npjma/wayland_bug_external_monitor_edge_cursor_wonkiness/
Can confirm on 5.27, and also on git master (though it happens less often than on 5.27, it does still happen)
