#webkitgtk — Public Fediverse posts

It seems I have found a sneaky memory leak that occurs when you reload webpages with @WebKitGTK: https://bugs.webkit.org/show_bug.cgi?id=319590

That might explain why I kept running out of RAM way too easily when using Epiphany with a dozen tabs or so.

I suspect fixing this should significantly improve Epiphany's survivability in the wild, as well as long-running GTK apps that embed a webview (like email clients) :blobcat:

For a long time I've been intrigued by #Epiphany taking 3 to 20 seconds to load most websites on startup or in Incognito Mode.

Today I tested a bunch of configurations to report a bug, profiled… and it turned out to be 2 bugs in 1 :blobsweats:

* The adblocker (and similar features) makes things slower :psyduck: : https://gitlab.gnome.org/GNOME/epiphany/-/work_items/2880#note_2766101

* WebKitGTK is doing some shenanigans with the system's fonts: https://bugs.webkit.org/show_bug.cgi?id=315135

#Sunstone browser now has a searchable history. The period to display can be set to the last hour, day, week, a custom timeframe or 'all'. There is also an option to group the results by host. By default, 50 results are displayed per page.

This is a WIP and subject to change. This biggest miss so far is a link in the page to navigate beyond the first page of results, although you can get there by appending 'page/<n>' to the url. The link to the host also needs fixed to point to the correct uri scheme. There are other missing features, such as the ability to delete history items or bookmarks, and while there is a growing list of settings there isn't anywhere to change them yet. One step at a time.

History and bookmarks are currently displayed in web page form. I'll be adding abbreviated displays in the sidebar eventually.

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

It's the first day of #FOSDEM2026 and you shouldn't miss our 4 talks! Our colleagues @philn @koala @mariospr and @regocas will cover #WebRTC, #WebKitGTK, #GStreamer, Interop, #MathML, Web Platform and @servo

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

Here is a list for Saturday:

Running #GNOMEOS on mobile phones https://fosdem.org/2026/schedule/event/ESE3GP-gnome-os-on-mobile/

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/

Managed to get #WebKitGTK to work with #puregotk. Just needed to add a small tweak since it was mixing up `gio.Byte` with `[]byte`. I think that makes it one of the first full-featured, CGo-free WebView libraries for Go?

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!

El jodido #WebKitGTK... pufff. A mí me suele tocar la moral bastante sus "fallitos".

Arreglan una cosa, rompen otra... meten algo nuevo que reemplazo algo viejo que iba fatal, pero con nuevos fallos.

Yo, de verdad, no lo veo usable a día de hoy como navegador. Es pasable para aplicaciones como esta o el lector de noticias que uso.

@mntmn That would explain why I've found GitLab's textfields to be an excellent stress-test performance benchmark for #WebKitGTK (reported as https://bugs.webkit.org/show_bug.cgi?id=301066). Sure, that website is bloated, but other web engines are so optimized that you don't usually notice it, so there's optimization potential in WebKitGTK :blobmiou:

I don't know what kind of wildly inefficient code #GitLab must have put in their bug reporting GUI, but it seems to be a great performance stress-test benchmark for @WebKitGTK, as Epiphany lags a *lot* when trying to type there :blobpats:

Reported it here: https://bugs.webkit.org/show_bug.cgi?id=301066

#WebKitGTK #GNOMEWeb

If you ever experienced broken / offset drag-and-drop previews in GNOME Web (Epiphany), particularly with kanban board applications like Trello for example, this is the bug report I filed about it in WebKitGTK: https://bugs.webkit.org/show_bug.cgi?id=292058

#GNOMEWeb #Epiphany #WebKitGTK #kanban #Trello

It took me years… YEARS to figure out a reliable way to trigger the #GNOMEWeb / #WebKitGTK bug where the native general "Copy/Back/Forward/Reload" right-click menu would show up on top of GMail's custom contextual menus.

Finally I found a 100% surefire way to make it happen. Now it seems so straightforward, all of a sudden :blobsweats:
