SUMMARY Dolphin unexpectedly opens "spring loaded" folders as new windows, as explained in the title. This may be a wayland thing and may be related to the bug (that I saw reported but can't find now) where holding SHIFT or CTRL during drag - on wayland - does not trigger the "force move" or "force copy" until you release the modifier key. STEPS TO REPRODUCE 1. Open Dolphin to a folder with some files and some folders. 2. Start dragging a file over an empty space 3. Hold SHIFT 4. Drag the file over a folder and immediately release the SHIFT key. OBSERVED RESULT Dolphin opens the folder that was dragged over in a new window. EXPECTED RESULT Dolphin should navigate to the folder that was dragged over in the same window - as it does if you don't release the SHIFT key. SOFTWARE/OS VERSIONS Operating System: KDE neon 5.27 KDE Plasma Version: 5.27.7 KDE Frameworks Version: 5.109.0 Qt Version: 5.15.10 Kernel Version: 6.4.11-060411-generic (64-bit) Graphics Platform: offscreen Processors: 20 × 12th Gen Intel® Core™ i7-12700H Memory: 31.0 GiB of RAM Graphics Processor: Mesa Intel® Graphics ADDITIONAL INFORMATION This behavior also allows to easily reproduce bug #462483 - if you then release the dragged file over the new window, the file operations menu will open in a window instead of a floating menu.
ALSO, I forgot to mention but it is more troubling - if you hold the drag over the destination folder, after you released the SHIFT key, and wiggle the mouse a bit, or move out of the folder and back on top of it, Dolphin will continue to create more and more new windows with every mouse move...
