Description

Foliate (installed from arch repos) is a book reader that uses webkitgtk-6.0 to render text.

Horrifying, I know. But it's the only one that didn't lag in large books, didn't look like ass, didn't randomly disrespect formatting, didn't try run my library by importing my books to some location without me asking it to do so, had actual GUI and not a meme-tier latin-only hotkeys, etc.

On scale 1 it works fine, without errors.

On anything above one you'll get this:

❯ foliate book.epub
Failed to create GBM buffer of size 0x0: Invalid argument
...

And a blank white page instead of your book.

I can observe this behavior on both wlroots (0.41.2) and aquamarine (hyprland 3b4aabe04c7756fb0a70d78b6f0e701228f46345, aquamarine 9312aa2).

Happens regardless if nvidia specific environment variables are set.

Now, if you look at foliate repo, there are issues about blank pages. https://github.com/johnfactotum/foliate/issues/1107, https://github.com/johnfactotum/foliate/issues/1115, https://github.com/johnfactotum/foliate/issues/1271, with some advice (bad if you don't like slideshow scroll) how to "fix" it - WEBKIT_DISABLE_DMABUF_RENDERER=1

So why make issue here?

Well, because it works on sway 1.9 with wlroots0.17 from arch repos on all scales.

I don't use nix, so because of the need for outdated dependencies I can't easily check when it started happening or if scales above 1 were always broken.

I certainly didn't use 1.25 I use now from the beginning of the fractional scaling support, so my comment on one of those issues might just be flatpak disrespecting scaling and working solely for that reason.

Even on sway+wlroots from 3 years ago it works fine on all scales, hyprland has this issue as early as 0.23beta, and probably always had. https://github.com/hyprwm/Hyprland/issues/7341#issuecomment-2347702040

Other WebKitGTK-6.0 apps

• epiphany (gnome web) has the same error on scales above 1, but manages to render the page properly. Might be some internal fallback that's just absent in foliate, idk.

• newsflash also works on scales above 1, but the whole interface is slightly blurry, which is strange, it's not xwayland. No GBM error.

• gfeeds works, interface as normal. No GBM error.

• setzer seems to work, but with interface slightly blurry like newsflash. No GBM error.

Again, I don't know if they just have some internal fallback - the performance is not horrible. But that's just simple webpages, not a million words long books.

But what curious is why sway works. Sway or wlroots, that don't support (proprietary) nvidia, so any nvidia specific fallback on their side is unlikely.

How to reproduce

Install foliate from arch repos (no flatpak/snap sandbox to interfere with anything) and use any .epub book.

Hyprland:

1. Set monitor = ,preferred,auto,1.25, (same for the scale 2)
2. Run foliate book.epub and observe the blank page and an error mentioned above
3. Close foliate
4. Set monitor = ,preferred,auto,1
5. Run foliate book.epub again and observe properly rendered book page

Sway:

If needed, copy default config to user config directory, since we will be editing it.

mkdir -p ~/.config/sway
cp /etc/sway/config ~/.config/sway/config

1. Replace default output statement with output * scale 1, press Super+Shift+C to reload config
2. Run foliate book.epub - page is displayed properly
3. Close foliate
4. Change the scale to 1.25, press Super+Shift+C to reload config
5. Because it's Sway, terminals now are blurry until you reopen them. We don't care about them.
6. Run foliate book.epub - page is still displayed properly
7. Change the scale to 2, press Super+Shift+C to reload config
8. Run foliate book.epub - page is still displayed properly

If you noticed that epiphany somehow doesn't output GBM error - idk why. I didn't change anything in configs, and this single commit that I upgraded to doesn't make sense as the cause. The only thing possibly related is mesa (1:24.1.5-2 -> 1:24.1.6-1) upgrade.

With foliate it's the same as outlined in the issue above, still.

There was an update in 'egl-wayland' 1.16 which fixed a QT6 Webengine bug https://github.com/NVIDIA/egl-wayland/releases/tag/1.1.16 worth a try in the meantime

[MahouShoujoMivutilde]

Status:

On d35e70a8c6599bb058cf86eb87c783ce1cf72471 (post 0.43.0), aquamarine 0.4.1, nvidia 560.35.03, egl-wayland 1.1.16, mesa 24.2.2, foliate 3.1.1, webkitgtk-6.0 2.44.4

The behavior is the same - scale 1 works fine, same GBM error on scales above 1 and empty window.

---

Also, something curious happens with nested sway window on host hyprland scales above 1:

Details

Hyprland scale 1, sway 1.25  Hyprland scale 1.25, sway 1.25  wtf?

This doesn't happen when sway in nested inside another sway.

Details

sway 1.25 inside sway 1.25 

[MahouShoujoMivutilde]

Tried to hunt it down, in vm, using 1 Jun 2024 box.

"Broken" here means scales above 1 reproduce the issue (blank page).

0.40.0 is broken - hyprwayland-scanner first introduced 0.37.1 is broken - before wlroots fork 0.33.1 is broken - there is no GBM error (still a blank page). Unfortunately, didn't pay attention if other earlier versions also had no error 0.27.2 is invalid - scale setting (1.25; 2) is ignored? - scale is 1, so it works 0.24.1 is broken 0.23beta is broken - earliest available in the arch linux archive

I think, it's safe to say, it never worked properly with scales above 1.

I also tested older versions of sway and wlroots:

sway 1.9 wlroots 0.17.1 works sway 1.7 wlroots 0.15.0 works (from almost 3 years ago)

Another note:

Foliate 2.6.4 that uses gtk3 3.24.41 and webkit2gtk 2.42.5 works on any scale, but works like a slideshow on large books, so I assume it has some fallback to software render internally that just didn't get ported to gtk4. I didn't investigate it further, as the performance is unusable anyway, and gpu render clearly can work (sway) on gtk4 too without any performance issues.
