--- Comment #1 from Gustaw Smolarczyk <wielkiegie at gmail.com> ---
I have looked at the trace. The source code line and struct offset imply that
dri2_egl_display::image_driver is NULL in dri2_surfaceless_create_surface
function. Of note is also the fact that a software renderer is used:

libEGL warning: No hardware driver found, falling back to software rendering

I see the following piece of code in dri2_wl_create_window_surface:

   if (dri2_dpy->image_driver)
      createNewDrawable = dri2_dpy->image_driver->createNewDrawable;
   else if (dri2_dpy->dri2)
      createNewDrawable = dri2_dpy->dri2->createNewDrawable;
   else
      createNewDrawable = dri2_dpy->swrast->createNewDrawable;

Shouldn't the surfaceless variant also try all three instead of relying on
image_driver not being NULL?

Note that I am not overly familiar with how dri works, so I might be wrong.
