            Bug ID: 487846
           Summary: Cursor teleports while dragging on bottom area of VLC
                    player
    Classification: I don't know
           Product: kde
           Version: unspecified
          Platform: Neon
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR

  Target Milestone: ---

SUMMARY
I can reproduce on kde-neon-unstable-2024-05-28 and on two instances of Fedora
40 on different computers. The KDE Neon had VLC preinstalled via it's repo, and
the Fedora installations have VLC from flathub. Dragging on the bottom part of
VLC player causes the cursor to 'jump' to the top left part of the window. This
might affect other programs too, haven't found one yet though. Please check the
attached video, where I demonstrate this strange behaviour.

STEPS TO REPRODUCE
1. Click and drag at the bottom part of VLC player, anywhere on the empty space
between the play/pause/stop etc. controls and volume bar on the right.

2. The cursor immediately jumps to the top left part of the window. The 'drag'
state is still respected so the window starts moving. This happens regardless
of the window being maximized or windowed.

OBSERVED RESULT
Cursor jumps/teleports to top left/middle left edge of window

EXPECTED RESULT
Maybe that part is intentionally drag-able to move the window, but the cursor
shouldn't jump to a different location
