Drag an image or folder 3. while dragging observe the cursor OBSERVED RESULT Cursor shows two different cursors icons while dragging EXPECTED RESULT Should drag smoothly without flickering [POC] https://youtu.be/9DEh7-drCHk
Moving the bug report to dolphin as it might be updating the cursor.
This seems similar to bug 449166, although for that one the item itself also shakes up and down, while in your recording the only thing that changes is the cursor.
Should be fixed in 5.24.6 or 5.25.0
