Stumbled upon another good example of a simple WordPress website theme causing scrolling performance problems in the latest version of GNOME Web (Epiphany), so I profiled the heck out of it with about 3.6 gigabytes of @WebKitGTK debug symbols installed: https://bugs.webkit.org/show_bug.cgi?id=310814

All my #WebKit merge requests have been merged. Now #WebKitGTK supports touch PointerEvent API, touch point coordinates are fractional, synthesized mouse events are unbroken and both WebKitGTK and WPE WebKit handle pointer capture and release according to the spec. This should considerably improve compatibility of #Epiphany (#GNOME Web) with touch interfaces.

There are still some more things to fix in there, maybe someone in #mobilelinux #linuxmobile community would like to give it a try?

Learn about all the cool projects #GNOME contributors have been working on by watching some talks at #FOSDEM!

Here is a list for Saturday:

Discovered today that Epiphany (and presumably any application using #WebKitGTK) will experience slow scrolling after resizing the webview (or window) on some websites, particularly when you drag the scrollbar using the mouse (instead of using the scrollwheel), as can be seen in the video below.

I have reported it here: https://bugs.webkit.org/show_bug.cgi?id=305290

Wondering if anyone experiences this on web pages other than this article: https://thewalrus.ca/return-to-office-mandates/

Ha, ran into a #WebKitGTK quirk today while extending the #puregotk generator to work with it: https://bugs.webkit.org/show_bug.cgi?id=175937

Workaround for now: https://github.com/pojntfx/ledger/commit/5a1608f4501f39500f0faf004d362b7b6cbd26ae

Funnily enough I ran into this exact problem with my own Go-based GObject library. Initialising them in `main` (yes, in a library!) fixed it there!
