      After a drag and drop operation on a QListView, the mouse starts acting weirdly. It's like the mouse button isn't released and by just moving the mouse around random QListView rows are selected and deselected.

      You can reproduce the issue by running the "Puzzle" (examples/itemviews/puzzle) example. Drag a piece of the puzzle and drop it. Start rapidly moving the mouse in and out of the left area. See the selection rectangle move strangely.

      IMO this is critical. Applications are made seriously unusable by this bug.

      This bug happens starting from 4.8.3. Version 4.8.2 behaves correctly.
