Cannot launch Cog or MiniBrowser - EGLDisplay Initialization failed: EGL_NOT_INITIALIZED

Hi. I am new to WPE and I am trying to build it to run it in Docker containers on various devices (currently limited to x86 - Intel Compute Stick STK1AW32SC and Intel NUC BLKNUC7i3DNK2E). The devices run a minimal Linux setup.

I am using Debian Buster, libwpe 1.2.1, wpebackend-fdo 1.2.2, wpewebkit 2.24.3 and cog 0.3.1. I can start weston fine, and the weston-simple-egl demo runs well. But when I try to start MiniBrowser or Cog, they fail with this error: EGLDisplay Initialization failed: EGL_NOT_INITIALIZED.

My Dockerfile is as follows:

FROM debian:buster

I run the container as privileged (docker run --privileged -it -v /dev:/dev my-wpe-image /bin/bash) and run the following commands in the container:

export XDG_RUNTIME_DIR=/tmp/weston
export WAYLAND_DEBUG=1
weston --backend=fbdev-backend.so --tty=7 --device=/dev/fb0 &
/usr/local/libexec/wpe-webkit-1.0/MiniBrowser https://www.google.com

The Wayland debug output looks like this:
