jerky video stream

[dhenin]

iMac 27' late 2013 sonoma
after trashing vlc and removing all videolan info: ":; find ~/Library/ -name "*videolan*" -exec rm -r {} \;"
and resettlement; "brew install vlc", the problem persists, that is to say that the sound of the freebox TV channels is audible (eg http://direct.franceculture.fr/live/fra ... -midfi.mp3), but, and that's the problem, the images are strongly jerky and invisible giving way to a disturbed gray background; The window moves on its own on the desktop
An idea ? an advice ?
THANKS

Do you have the same issue when using an official build of VLC from www.videolan.org instead of something from homebrew?
