glmark2 packages are missing dependencies on GL libraries

Sounds like the disk image lacks OpenGL support? Also try running:

  sudo apt install mesa-utils
  es2_info

  sudo apt install weston
  weston-simple-egl

I meant that installing libgl1 and libegl1 manually makes glmark2 and glmark2-wayland work. Those packages just aren't installed as dependencies to glmark2.

While that sounds sensible, I would focus on bug 1951402 first. That may automatically solve this.

Also I wonder what other apps might be broken by basic OpenGL libraries missing in WSL.

When you install Ubuntu-22.04 as a WSL 2 distro, it contains a certain package set.
But after it's installed, and you start using apt-get, you'll start use the normal
Ubuntu repos. So everything after the initial install comes from the Ubuntu repos.
WSL 2 Ubuntu-22.04 image is not a static kind of setup you can't change.

I can see how this happened. The packaging automatically creates dependencies on the build-time shared libraries, but glmark2 doesn't choose its GL libraries until runtime. So the binary package dependencies are wrong. And it looks like the same mistake persists in the newer upstream version: https://tracker.debian.org/pkg/glmark2

So waiting for bug 1951402 probably won't fix this, but it's still something I would recommend happens first.
