Varem tagati stabiilne riistvaraline video kiirendamine vaid uue backend'i kaudu, mis kasutas Waylandi ja DMABUFi mehhanismi. X11 puhul ei rakendatud kiirendust gfx-draiverite probleemide t\u00f5ttu. N\u00fc\u00fcd on X11 jaoks video kiirendamise probleem lahendatud kasutamine<\/a><\/noindex> EGL kaudu. Samuti on X11 s\u00fcsteemide jaoks rakendatud WebGLi t\u00f6\u00f6v\u00f5imekus l\u00e4bi EGL, mis tulevikus v\u00f5imaldab X11-le lisada ka riistvaralise WebGL kiirenduse toe.
\nPraegu on see v\u00f5imalus siiski vaikimisi keelatud (l\u00fclitatakse sisse widget.dmabuf-webgl.enabled kaudu), kuna mitte k\u00f5ik probleemid pole veel lahendatud.<\/p>\n

EGL kaudu t\u00f6\u00f6tamise aktiveerimiseks on ette n\u00e4htud keskkonnamuutuja MOZ_X11_EGL, mille seadistamise j\u00e4rel Webrender

WebRender on kirjutatud Rust'i keeles ning v\u00f5imaldab saavutada m\u00e4rkimisv\u00e4\u00e4rset kiiruset\u00f5usu ja v\u00e4hendada CPU koormust, viies GPU-le lehe sisu renderdamise operatsioonid, mis on teostatud GPU shaderite kaudu. Varasemalt oli WebRender kaasatud Windows 10 platvormile Intel GPU-dele, APU AMD Raven Ridge'ile, AMD Evergreen'ile ja NVIDIA graafikakaartidega s\u00fclearvutitele. Linuxis on WebRender hetkel aktiivne ainult Intel ja AMD kaartide jaoks \u00f6\u00f6ehitustes ja NVIDIA kaartide jaoks ei ole toetust. Rakendamiseks about:config'is tuleb aktiveerida seaded \u201egfx.webrender.all\u201d ja \u201egfx.webrender.enabled\u201d v\u00f5i k\u00e4ivitada Firefox muutujaga MOZ_WEBRENDER=1. <\/p>\n
