            Bug ID: 463628
           Summary: Mouse cursor randomly remains stuck in wrong state
                    after a drag-n-drop
    Classification: Applications
           Product: dolphin
           Version: 22.08.3
          Platform: Manjaro

            Status: REPORTED

STEPS TO REPRODUCE
I don't know, this happens randomly and sporadically.
I guess this makes it more likely to happen:

1.  use Dolphin
2.  Move files and folders around by drag-n-drop, even into external
applications, e.g. dragging them into FileZilla to upload them
3.  try to make crazy, fast movements. For example, hover over some folder on
the "breadcrumb" at the top of the Dolphin window so that a submenu with the
subfolders shows up, but move away before it's completely open (that alone
doesn't reproduce the issue); try to move the mouse when you release the
button; try to make things happen in an unlikely order which you failed to
consider as possible.

OBSERVED RESULT

Sometimes the mouse cursor remains "stuck" in a state that it should no longer
be in, with the green circle with a "+" inside, indicating that you are
dragging something that will be copied to the destination when you'll drop it.
Except that you are no longer dragging anything


EXPECTED RESULT

This should never, ever happen. The displayed state of the cursor should always
be consistent with the actual state of things, and you should guarantee that at
the deepest level. Also, you shouldn't trust yourselves and you should take
every opportunity to update the state so that, if a wrong state has "leaked",
it will get corrected e.g. the next time you click or something. It's
absolutely ridiculous that the "leaked" state can remain for so long. I found
no way to correct it other than closing all Dolphin windows, which is very
destructive.
