Sur une installation fraîche de Ubuntu je constate un problème de tearing, notamment sur molotov mais pas sur mpv.
Initialement, le problème était visible partout mais en modifiant les options du kernel, le problème sur mpv a été résolu.

Je ne sais pas comment configurer correctement la carte graphique...
L'un d'entre vous pourrait-il m'aider?
