Created attachment 120280 [details] Demonstration 1 SUMMARY When restarting plasmashell, logging out or rebooting the folder view widget in list view mode stops working properly and shift-clicking to select multiple items at once becomes unreliable. Doing this will also make keyboard navigation stop working as described in bug 367851. STEPS TO REPRODUCE 1. Add a Folder View widget with list view mode pointing to any directory containing some files. 2. Do any of the following: Restart plasmashell via terminal (kquitapp5 plasmashell and then kstart5 plasmashell), or log out and log back in, or reboot the computer. OBSERVED RESULT Shift-clicking no longer works reliably. EXPECTED RESULT Shift-clicking still works normally. SOFTWARE/OS VERSIONS KDE Neon Testing KDE Plasma Version: 5.15.90 KDE Frameworks Version: 5.59.0 Qt Version: 5.12.0 ADDITIONAL INFORMATION
After a system update I can't reproduce this anymore on KDE Neon Testing. However on another installation running Manjaro Stable I can still reproduce it every time, so I assume it has been fixed.
Thanks for the update Alex!
Reopening, apparently I just got lucky when resizing panels back then. At least I have more information on how to reproduce it now. Using a panel attached to the left or right screen edge and not making the panel "thick" enough will consistently reproduce this bug, at least on my machine. Don't know if things like screen resolution matter or not. Panels attached to the top or bottom edge work fine regardless of thickness.
I can reproduce this very strange issue in git master by following those instructions.
