I noticed that surf assumes that it's running under an X11 display in
places like this:

   https://sources.debian.org/src/surf/2.1%2Bgit20221016-4/surf.c/#L1403

It doesn't work for me at all in a Wayland environment, even if
Xwayland is available.

I think that this is orthogonal to this GL problem we're talking
about, but surf should force the GDK backend to X11 because that's the
only one that it supports. gdk_set_allowed_backends() before gtk_init()
should be enough:

   gdk_set_allowed_backends("x11");
   gtk_init(NULL, NULL);

https://sources.debian.org/src/surf/2.1%2Bgit20221016-4/surf.c/#L350

Or the GDK_BACKEND=x11 variable for a quick test.
