STEPS TO REPRODUCE 1. start Wayland session 2. use Dolphin to open a folder containing 1 file and 2 subfolders named "folderA" and "folderB" 3. right-click on an empty area, hover over "Sort by", set sorting by name, select "A-Z" and check "Folders first" 4. start to drag the file, position cursor in the most left position of "folderB" icon (notice that "folderA" is unexpectedly highligthed), release the mouse button (cursor jumps to "folderA"), choose "copy/move here" OBSERVED RESULT the dropped file is copied/moved to "folderA" EXPECTED RESULT the cursor should not jump to "folderA" when mouse button is releaded, so the dropped file is copied/moved to "folderB" when we choose "copy/move here" SOFTWARE/OS VERSIONS Operating System: KDE neon Unstable Edition KDE Plasma Version: 5.19.80 KDE Frameworks Version: 5.71.0 Qt Version: 5.14.2
Reproduced, in dolphin and gwenview (so not QGraphicScene specific) The drop zone seems to be only covering the right half of the expected drop zone, the left half zone points to the element to the left or no element when there is none. Seems like a Qt bug.
I can't reproduce this bug on neon unstable anymore. Can anyone?
I can't reproduce anymore either. Seems like Qt 5.15+ or KWin 5.20+ fixed the bug.
