Razvijeni od strane Apple-a, web preglednik WebKit koristi se u preglednicima poput Safarija i Epiphany (GNOME Web) te prelazi na kori\u0161tenje biblioteke Skia za prikaz 2D grafike, koja se koristi u Google Chrome-u, ChromeOS-u, Android-u i Flutter-u, a podr\u017eava prikaz putem GPU-a. Portiranje je izvr\u0161ila tvrtka Igalia u okviru inicijative za optimizaciju performansi WebKitGTK za GNOME. Kao razlog migracije navodi se dostizanje limita u procesu optimizacije performansi 2D prikaza putem CPU-a, te potreba za kori\u0161tenjem GPU-a za daljnje pobolj\u0161anje performansi. <\/p>\n

Poku\u0161aji dodavanja mogu\u0107nosti 2D prikaza putem GPU-a u biblioteku Cairo, koja se koristila u WebKitu, nisu uspjeli zbog arhitektonskih zna\u010dajki te biblioteke, a projekt izrade vlastite biblioteke za prikaz je odba\u010den zbog pote\u0161ko\u0107a u postizanju ravnote\u017ee izme\u0111u performansi i kvalitete prikaza. Na kraju su se programeri iz Igalia vratili ideji kori\u0161tenja biblioteke Skia, koja je bila optimalno rje\u0161enje, ali je prvotno odbijena zbog nedostatka stabilnog API-a, problema s kori\u0161tenjem kao vanjske zavisnosti i potrebe za podr\u0161kom vanjskog modula u WebKitu. <\/p>\n

Odlu\u010divanje o prebacivanju WebKita na biblioteku Skia olak\u0161ano je time \u0161to su nedostaci povezani sa zamjenom zavisnosti nadma\u0161ili prednosti, koje su se manifestovale ne samo u pove\u0107anju performansi prikaza, ve\u0107 i u pojednostavljenju k\u00f4dne baze i pro\u0161irenju mogu\u0107nosti za razvoj nove funkcionalnosti. \u0160to se ti\u010de performansi, inicijalni port WebKita na Skia tijekom testova MotionMark na PC-u pokazao je dvostruko ubrzanje prikaza u odnosu na stari k\u00f4d koji koristi CPU. <\/p>\n

U velja\u010di 2024. godine, grana WebKita preba\u010dena na Skia dostigla je spremnost za integraciju u glavni sastav k\u00f4dne baze WebKita. Nakon rasprave s programerima iz Google-a, Sony-a, Apple-a i Red Hat-a donesena je odluka o prijelazu WebKita s biblioteke Cairo na Skia i trenutno je kod za podr\u0161ku Skia ve\u0107 prihva\u0107en u glavnu granu WebKita.
