Update on what happened in WebKit in the week from March 3 to March 10.
Cross-Port 🐱
Web Platform 🌐
Forced styling to field-sizing: fixed when an input element is auto filled, and added
support for changing field-sizing
dynamically.
Fixed an issue where the imperative
popover APIs didn't take into account the source parameter for focus behavior.
Multimedia 🎥
GStreamer-based multimedia support for WebKit, including (but not limited to) playback, capture, WebAudio, WebCodecs, and WebRTC.
Fixed YouTube breakage on videos with advertisements. The fix prevents scrolling to the comments section when the videos are fullscreened, but having working video playback was considered more important for now.
Graphics 🖼️
Fixed re-layout issues for form
controls with the experimental field-sizing implementation.
Landed a change that improves the quality of damage rectangles and reduces the amount of painting done in the compositor in some simple scenarios.
Introduce a hybrid threaded rendering mode, scheduling tasks to both the CPU and GPU worker pools. By default we use CPU-affine rendering on WPE, and GPU-affine rendering on the GTK port, saturating the CPU/GPU worker pool first, before switching to the GPU/CPU.
Infrastructure 🏗️
We have recently enabled automatic nightly runs of WPT tests with WPE for the Web Platform Tests (WPT) dashboard. If you click on the “Edit” button at the wpt.fyi dashboard now there is the option to select WPE.
For example, one may compare the results for WPE to other browsers or examine the differences between the WPE and GTK ports.
These nightly runs happen now daily on the TaskCluster CI sponsored by Mozilla (Thanks to James Graham!). If you want to run WPT tests with WPE WebKit locally, there are instructions at the WPT documentation.
That’s all for this week!
