Where did you start the drag? Key question is where we dragged over. Code path in kwin says: Find the window at the given position, then do something with the surface. Somehow we got a window returned with no surface. Internal window maybe? The drag was started in Dolphin. As I recall, it didn't reach the Plasma desktop before crashing. I think it went over Dolphin's Places panel. Or if it did, it was just at the moment the drag moved over a pixel of the desktop. *** Bug 510107 has been marked as a duplicate of this bug. *** A possibly relevant merge request was started @ https://invent.kde.org/plasma/kwin/-/merge_requests/8191 Git commit 2c04714d1dfef8546470daa9b5678e57760233fc by Vlad Zahorodnii.
