Publi\u00e9<\/a><\/noindex> lancement du gestionnaire de fen\u00eatres xfwm4 4.14.3<\/a><\/noindex>, utilis\u00e9 dans l'environnement utilisateur Xfce pour assurer l'affichage des fen\u00eatres \u00e0 l'\u00e9cran, la d\u00e9coration des fen\u00eatres et l'organisation de leur d\u00e9placement, fermeture et redimensionnement. <\/p>\n

Dans cette nouvelle version ajout\u00e9<\/a><\/noindex> prise en charge de l'extension X11 XRes<\/a><\/noindex> (X-Resource), qui est activ\u00e9e<\/a><\/noindex> pour demander au serveur X des informations sur le PID d'une application lanc\u00e9e en utilisant des m\u00e9canismes d'isolement sandbox. Le support de XRes r\u00e9sout le probl\u00e8me de la terminaison forc\u00e9e des processus clients bloqu\u00e9s, dont le PID ne peut pas \u00eatre obtenu via la propri\u00e9t\u00e9 _NET_WM_PID, car il refl\u00e8te l'identifiant du processus dans un environnement isol\u00e9, qui peut diff\u00e9rer de l'identifiant dans l'espace de noms global. <\/p>\n

Dans cette nouvelle version, il y a \u00e9galement a \u00e9t\u00e9 corrig\u00e9e<\/a><\/noindex> une vuln\u00e9rabilit\u00e9 qui peut conduire \u00e0 un acc\u00e8s \u00e0 un espace m\u00e9moire d\u00e9j\u00e0 lib\u00e9r\u00e9 (use-after-free) et \u00e0 l'\u00e9criture de donn\u00e9es en dehors d'un tampon allou\u00e9 lors du traitement de cha\u00eenes de param\u00e8tres. De plus, dans xfwm4 4.14.3 ajout\u00e9es<\/a><\/noindex> des gestionnaires d'erreurs suppl\u00e9mentaires XError, facilitant le diagnostic des probl\u00e8mes li\u00e9s aux requ\u00eates XConfigureWindow.<\/p>\n

Certains utilisateurs ont constat\u00e9 qu'apr\u00e8s la mise \u00e0 jour vers la version 4.14.3 ils ont rencontr\u00e9<\/a><\/noindex> des plantages lors de la tentative de d\u00e9marrage sous FreeBSD, apparemment dus \u00e0 un nouveau lien avec libXres. De plus, dans xfwm4 une grave<\/a><\/noindex> il y a un probl\u00e8me de d\u00e9tection des cartes graphiques AMD lors de l'activation de l'extension X11 XPresent pour synchroniser l'affichage avec le pulse de suppression d'images (vblank). XPresent \u00e9tait activ\u00e9 lorsque le nom de la carte comportait un masque AMD, tandis que certaines cartes sont nomm\u00e9es<\/a><\/noindex> \u00abRadeon\u00bb sans mention du mot \u00abAMD\u00bb (par exemple, \u00abRadeon RX 570\u00bb). Pour ces cartes, le gestionnaire vblank bas\u00e9 sur \u00abglx\u00bb \u00e9tait activ\u00e9, ce qui entra\u00eene une performance significativement inf\u00e9rieure.<\/p>\n

Par exemple, avec glx, la lecture de vid\u00e9o 4K dans mpv sollicite le GPU \u00e0 70 % en qualit\u00e9 \u00e9lev\u00e9e et \u00e0 50 % en qualit\u00e9 basse, tandis que la charge lors de l'utilisation de XPresent diminue respectivement \u00e0 50 % et 30 %, ce qui a un impact significatif sur la consommation \u00e9nerg\u00e9tique et les performances. Le probl\u00e8me reste non r\u00e9solu. Pour forcer l'activation de XPresent, vous pouvez ajouter le param\u00e8tre \/general\/vblank_mode dans xfconf :<\/p>\n

xfconf-query -c xfwm4 -p \/general\/vblank_mode -t string -s \u00abxpresent\u00bb \u2014create<\/p>\n
