L'uso di Ozone consente di supportare X11 e Wayland in un'unica versione di Chrome, senza legarsi a un particolare sottosistema grafico. Il vecchio backend, che supportava solo il funzionamento tramite X11, \u00e8 previsto per essere classificato come obsoleto e rimosso dalla base di codice nel tempo.        <\/p>\n<p>L\u2019indipendenza dalle peculiarit\u00e0 della costruzione dell'interfaccia grafica nei vari sistemi operativi in Chrome \u00e8 realizzata grazie a un proprio stack grafico cross-platform chiamato Aura. Aura svolge le funzioni di un gestore delle finestre (Aura shell), operando tramite un compositore proprietario <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/it\/server\/\"   title=\"un server\" data-wpil-keyword-link=\"linked\">un server<\/a> e utilizzando le risorse GPU disponibili per accelerare le operazioni grafiche. Per la creazione degli elementi dell'interfaccia viene utilizzato il toolkit grafico Aura UI, che fornisce un insieme di widget, finestre di dialogo, controlli e gestori degli eventi. Dallo stack grafico sottostante (X11, Wayland, Cocoa o Windows) viene utilizzato solo l'output sopra la finestra principale.    <\/p>\n<p>Tutte le operazioni specifiche con lo stack grafico di Linux sono ridotte a un'astrazione facilmente sostituibile chiamata Ozone. Finora, il supporto per Ozone era fornito come opzione, mentre per impostazione predefinita veniva utilizzato il vecchio backend, rigidamente legato a X11. I lavori per la conversione delle build da X11 all'uso del layer Ozone sono iniziati nel 2020, e per gli utenti, l'abilitazione graduale del backend Ozone\/X11 come predefinito \u00e8 cominciata con il rilascio di Chrome 92. Pochi giorni fa, il nuovo backend \u00e8 stato attivato per tutti gli utenti Linux di Chrome. Oltre a X11 e Wayland (--ozone-platform=wayland e --ozone-platform=x11), in Ozone si stanno inoltre sviluppando piattaforme per l'output attraverso i driver grafici KMS\/DRM, l'output in forma di grafica ASCII tramite la libreria libcaca, il rendering in immagini PNG (Headless) e la trasmissione tramite dispositivi Chromecast.                    <center><img decoding=\"async\" alt=\"Chrome
