Changed paths: M Source/WebKit/WebProcess/Plugins/PDF/UnifiedPDF/UnifiedPDFPlugin.mm Log Message: ----------- [UnifiedPDF] Graphics layers being painted into should use asynchronous drawing https://bugs.webkit.org/show_bug.cgi?id=273916 rdar://127767482 Reviewed by Simon Fraser. After 278263@main, we no longer need to provide PDFKit with a platform context, and thus have no need for WP-backed graphics layers. This means that we can use asynchronous drawing for all layers we paint things into, which includes the layers for content, page background, and selection. Our primary motivation to make this change is improved performance when rendering PDFs. In this patch, we enable asynchronous drawing for the aforementioned graphics layers. We do so unconditionally for the selection and page background layers, since they never need a platform context. For the content layer, we condition enablement of asynchronous drawing on our runtime ability to paint selections into their own layer, since in that case we need not pass a platform context to PDFKit. * Source/WebKit/WebProcess/Plugins/PDF/UnifiedPDF/UnifiedPDFPlugin.mm: (WebKit::UnifiedPDFPlugin::ensureLayers): (WebKit::UnifiedPDFPlugin::updatePageBackgroundLayers): (WebKit::UnifiedPDFPlugin::layerNeedsPlatformContext const): (WebKit::UnifiedPDFPlugin::updateOverflowControlsLayers): (WebKit::UnifiedPDFPlugin::positionOverflowControlsLayers): Canonical link: https://commits.webkit.org/278569@main To unsubscribe from these emails, change your notification settings at https://github.com/WebKit/WebKit/settings/notifications _______________________________________________ webkit-changes mailing list webkit-changes@lists.webkit.org https://lists.webkit.org/mailman/listinfo/webkit-changes
