abstraction layer to allow multiple rendering backends (Nicosia). Produced documentation for the WPE and GTK ports ( ). Use Skia DisplayList to record drawing operations Thread-safe recording of drawing operations per frame (vs WebCore's). Threaded GPU painting and hybrid mode Support enabling GPU rasterization using Skia backend in multiple threads. Enabled multiple modes that can use CPU, GPU or a mix of both. Damage tracking for dirty regions Track damaged regions through the pipeline and use them for composition. link Igalia and WebKit: status update and plans Igalia, WebKit Contributors Meeting 2025 17 / 40
in the graphics pipeline to avoid unneeded waits. Improved format negotiation for buffers in embedded devices Prioritize formats allowing direct scanout. Implement negotiation in the backends (supports Wayland & DRM). AHardwareBuffer support for Android Added support for Android graphics sharing buffer (i.e. zero-copy). Enables usage of the new WPEPlatform API in Android. Enables usage of WebXR implementation in Android. Enabled GPUProcess by default for WebGL This is done as of last week ( ). commit Igalia and WebKit: status update and plans Igalia, WebKit Contributors Meeting 2025 18 / 40

aiming to finish it in the next months. New tooling to detect memory leaks and do profiling Added strong root logging tool for finding memory leaks. Added JSC symbols integration in sysprof (still WIP). Working on ports of sysprof and samply to armv7. WASM-related work for 32-bit support, e.g.: Kept BBQJIT in good shape on ARMv7. Completed port of OMG. Started working on IPInt (WIP). WebKit bugzilla Igalia and WebKit: status update and plans Igalia, WebKit Contributors Meeting 2025 21 / 40
is to align better with 64-bit and simplify the maintenance. Current plan is to have an initial implementation soon and evolve iteratively. Still work in progress, will be our main focus in the upcoming months. Other: Added arm64 support for the WebKit Container SDK. Added support for the GDB JIT API. Fixed several bugs on 64-bit detected by 32-bit failures. Fixed memory leaks for long-running applications. Igalia and WebKit: status update and plans Igalia, WebKit Contributors Meeting 2025 22 / 40

integration pending). Enables using the new WPEPlatform API on Android. Native integration with Android subsystems e.g. logging integration with Android logging Upstreamed changes to WebKit Dropped all the downstream patches from the WPE Android project. Continued evolving the WPE Android project Goal: WebKit-based native alternative to Android WebView. Updated to WPE (2.50) and Android LTS NDK r27 ( ). Ongoing migration to the WPE Platform API ( ). ⚠️ Ongoing effort, still experimental support ⚠️ releases work in progress Igalia and WebKit: status update and plans Igalia, WebKit Contributors Meeting 2025 24 / 40
new WPEPlatform API Reproducible environment based on OCI containers. Same environment for developers and bots. New scalable cloud-based infrastructure Kubernetes as orchestrator for the QA infrastructure. Automatically adjust resources depending on the load. Better management and observability. Gardened lots of tests (skipped and failing tests) Much better situation since July 2025. Igalia and WebKit: status update and plans Igalia, WebKit Contributors Meeting 2025 25 / 40
six months (March, September). Minor (bug & security fixes) and development releases as needed. Security fixes are reaching users faster: Best case releases on the next or even the same day as embargo lifts. WebKit Security Advisories (WSA): Released 11 security advisories (WSAs), covering 54 CVEs. Other improvements in the Linux ports (WebKitGTK & WPE): Completely dropped libsoup2 support from the tree.
