I have the same exact behavior, however this behavior only happens to me on wayland.

Im running Arch Linux with KDE Plasma, and when i start a session on x11 on a fresh boot skiff desktop works fine and launches (both on flatpak and manual build), but if i do a fresh boot and launch into Wayland, it will not work and i get the behavior as stated above.

Edit : A temporary workaround at least on my end, is to set KDE plasma display settings for monitor to 100% scaling when in the Plasma Wayland session, and then application then launches when i relaunch skiff-desktop. However, upon closure and if i were to attempt to launch anything higher than 100%, it will refuse to launch as the above image shows as well.

That's really interesting. This is my test results:

• ❌ KDE (Wayland)
• ❌ KDE (X11)
• ⭕ Wayfire
• ⭕ Sway
• ⭕ Budgie

So it basically works on every single desktop environment / window manager other than KDE Plasma. My display scaling is set to 100% all the time. I cannot set it to be lower than 100%.

Update: I have manually built Skiff myself and it works, meaning the issue only exists for the Flatpak version on KDE Plasma for me.

I can confirm too, get the same thing, any other environment works ( hyprland , i3-wm ) all work but kde is being silly on my end as well. I'll try manually building and see if it works good on my end :)

Hm, can you test the GNOME Web Flatpak on Plasma? It also uses webkitgtk.

[madonuko]

Can confirm GNOME Web just crashes with the same flatpak-spawn error, might be an issue with webkitgtk in flatpaks?

i confirm this happen to me to on Nobara KDE (modified) wayland if someone know a work around i would take it.

edit : the simple 100% ui scale work for me
