Created attachment 146865 [details] Screenshot SUMMARY Having two Dolphin windows opened, I tried drag and drop one file from one window to the another: Dragged the file over the Dolphin icon in the taskmanager, so that the pop up of the window list opens and finally dragged it on the right item in the list, and dropped it in the raised window. However, the popup window list no longer vanishes, it stays opened all the time. SOFTWARE/OS VERSIONS Operating System: openSUSE Tumbleweed 20220214 KDE Plasma Version: 5.24.0 KDE Frameworks Version: 5.90.0 Qt Version: 5.15.2 Kernel Version: 5.16.8-1-default (64-bit) Graphics Platform: Wayland Graphics Processor: AMD Radeon RX 580 Series
Also, the popup is not correctly aligned and actually touches the panel, but this may be a different bug.
The popup vanished, when I closed the Dolphin window from which I dragged the file.
Fushan, didn't you investigate this at some point? I seem to recall a Bugzilla ticket for it, but now I can't find it anymore.
This has been fixed for a while and I'm not able to reproduce the issue in Plasma 5.27.4.
