@xerz There has been quite a lot of improvements under the hood in @WebKitGTK, many related with performance and supported web features, but the GNOME release notes don't even mention that the GTK4 support was a major undertaking, and that we have everything lined up for zero copy operation, including accelerated media playback. This teaser was shared some days ago in Reddit: https://www.reddit.com/r/gnome/comments/11pav5t/gnome_web_44_leaps_and_bounds/
We still have further.improvements lined up, and some of the new things require tweaks to enable them for testing, but it's looking quite promising. Oh, and the GStreamer based WebRTC support keeps improving with each release... Getting there!
Also: we should write a blog post soon about all the goodies in WebKitGTK 2.40.x :thinkhappy:
