Created attachment 158943 [details] screenshot SUMMARY I can't reproduce this issue consistently, but it occurs often after the following steps. STEPS TO REPRODUCE 1. with Dolphin, create a new folder and open it 2. press F4 to open the Terminal panel and create 10,000 files by running the following command: $ for i in {1..10000}; do touch $i; done 3. create a subfolder 4. move hundreds or thousands of those 10,000 files to this subfolder (with keyboard shortcuts or drag-and-drop) OBSERVED RESULT plasmashell process causes high cpu usage while the files are moved, and Plasma is slow until the cpu usage decreases to the normal level. Please se the attached screenshot showing the high cpu usage. EXPECTED RESULT plasmashell process with normal cpu usage and performance while the files are moved SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.27.5 KDE Frameworks Version: 5.106.0 Qt Version: 5.15.9 Graphics Platform: Wayland
Well with Dolphin with Qt6, I can consistently crash Dolphin by dragging all of them. :/ But I can't reproduce ay slowness in plasmashell when I drag like a thousand of them.
