            Bug ID: 285154
           Summary: [GTK] Fails if OpenGL is unavailable
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: PC
                OS: Linux
            Status: NEW
          Keywords: Gtk
          Severity: Normal
          Priority: P3
         Component: Accessibility
          Assignee: webkit-unassigned at lists.webkit.org

When OpenGL support is missing or explicitly disabled, WebKitGTK fails to initialize and aborts, e.g. by running the following command:

$ env LIBGL_ALWAYS_SOFTWARE=1 GALLIUM_DRIVER=none epiphany

I can see the following output on the console:
libEGL warning: egl: failed to create dri2 screen
Could not create surfaceless EGL display: EGL_NOT_INITIALIZED. Aborting...

I would expect that WebKitGTK should work in this case, and only the 3D features would be disabled.

Package versions:
- webkitgtk-6.0 2.46.5
- gtk4 4.16.7
- mesa 24.3.2

Distribution: Arch Linux
