--- Comment #1 from Carlos Alberto Lopez Perez <clopez at igalia.com> ---
That's expected.

To run without OpenGL you have to disable the hardware acceleration, and WebKitGTK defaults to enable it (so it will crash if you don't have OpenGL and you don't disable the acceleration).

You can disable that either by exporting the environment variable WEBKIT_DISABLE_COMPOSITING_MODE=1 before running your program or by disabling the hardware-acceleration-policy setting when constructing the webview.
Check: https://webkitgtk.org/reference/webkit2gtk/stable/WebKitSettings.html#WebKitSettings--hardware-acceleration-policy

Note that if you disable the acceleration some things like CSS 3D transforms may work incorrectly. For example you will see a flat animation here: https://webkit.org/blog-files/3d-transforms/poster-circle.html
