When the "Wall" is enabled in "Video Effect", closing any sub-window will cause the VLC interface to lose control.

- VLC: 3.0.18 (From snap, current latest)
VLC has some rare settings in Video Effect. When "Wall" is enabled, if you close any of the pop-up sub-windows, this will cause the video of other sub-windows to freeze, and the interface of the VLC main window will also lose control.
A runaway VLC will not shut down properly. Whether by closing the main window, using the resident icon in the tray, or even using the command killall vlc, VLC cannot be closed normally.
So far the only way I've found to properly shut down a runaway VLC is through the following command:
kill -9 $(pgrep vlc)
