Spider Web Flatpak freezes on workspace switch in Hyprland (Wayland)

[revanthlol]

When running Spider Web via Flatpak on Arch Linux with Hyprland, the app freezes after switching workspaces. The only temporary fix is clicking the maximize button.

The problem appears related to GTK, Wayland/X11 backend handling, and AT-SPI (accessibility) registration.
Clicking the maximize button temporarily restores interactivity.

Terminal output shows GTK / AT-SPI warnings:

Gtk-WARNING **: Error embedding AT-SPI socket: GDBus.Error:org.freedesktop.DBus.Error.NameHasNoOwner
Gtk-WARNING **: Failed to open display

Mesa Vulkan warnings (Intel GPU):

MESA-INTEL: warning: support YUV colorspace with DRM format modifiers
MESA-INTEL: warning: support more multi-planar formats with DRM modifiers

Environment

• OS: Arch Linux
• Compositor: Hyprland (Wayland)
• GPU/Driver: Intel, Mesa (Vulkan support)
• Flatpak app: Spider Web (io.github.zaedus.spider)
• Flatpak runtime: Freedesktop / GNOME (tested multiple versions)

Workarounds Tried

1. Force X11 backend and fallback socket:

   flatpak override --user --env=GDK_BACKEND=x11 io.github.zaedus.spider
   flatpak override --user --socket=fallback-x11 io.github.zaedus.spider

2. Force Wayland backend:

   flatpak override --user --env=GDK_BACKEND=wayland io.github.zaedus.spider
   flatpak override --user --socket=wayland io.github.zaedus.spider

3. Reinstall at-spi2-core (accessibility):

   sudo pacman -S at-spi2-core

4. Tried both Freedesktop and GNOME runtimes in Flatpak.
