Bug 233127 – [GTK] Web pages too laggy

• Status: RESOLVED
• Resolution: MOVED
• Component: WebKitGTK

[tarch1]

Hi,
I'm running Epiphany browser that work very great in most sites but it will become unusable in those sites: youtube - generic newspaper sites (like investing.com for example)
I'm running a i5-8300h paired an nvidia 1050.
The system is Arch, linux kernel 5.14.16, with gnome-shell, mutter and relative gnome packages, I've used it with Wayland.
With one tab open on google.com uses 180 MB and webkitwebprocess uses 500 MB, resource monitor used is bpytop
App version: epiphany 41.0 - webkitgtk 2.34.1 - mutter 41.1 - gnome-shell 41.1
Hopeful this will be useful

Sounds like something might be wrong with accelerated compositing mode. Does it work better if you run with WEBKIT_DISABLE_COMPOSITING_MODE=1?

[tarch1]

Not so much, abount newspaper pages work like without the option, for video is different, now the sound go regular and video lag too much that at 20 sec it show the frame of third

Lauching from terminal show these error:

Well that one's on you.

That's pretty bad. Check if your portals are running:

$ systemctl --user status xdg-desktop-portal.service
$ systemctl --user status xdg-desktop-portal-gnome.service

[tarch1]

I have the gtk gnome and kde of xdg-desktop-portal but no systemd related service

[tarch1]

i don't know if its possible to run on openrc

You are using openrc on... Arch? How do you start the desktop portals then?

Truth is that when you venture too far into unusual territory, you're going to have unusual bugs. I'm going to suggest you figure out how to run those portals in order to get rid of the settings error, then report back once you have settings working.

[tarch1]

No, sorry 
I wrote the frong distro, is Artix instead of arch.
To be honest I don't have the knowledge about portals, so I  don't know if is gnome that start it or it doesn't run at all

[tarch1]

I've found that portal, portal-gnome and portal-gtk, are launched by gdm, so maybe is another problem

similar problem

nvidia gt1030 on wayland

Minibrowser consume huge cpu while scroll and any other action.

this issue reproduce in webkit2gtk-4.1 and webkit2gtk 4.0  on archlinux

and work well on webkit2gtk-5.0.

and  all of them , the hardware acceleration is proper in  webkit://gpu 

maybe it affect by gtk
