So, I should probably report this bug to Ferral Interactive (studio respons=
ible
for the Linux port), right?

The correct override is:
# force_glsl_extensions_warn=3Dtrue
MESA_EXTENSION_OVERRIDE=3DGL_ARB_arrays_of_arrays
Setting force_glsl_extension_warn=3D1 leads to an error. And indeed, setting
those two environment variables leads to visible characters in the game, see
the attached screenshot.
Should this bug be renamed to =C2=BB[radeonsi] Implement GL_ARB_arrays_of_a=
rrays for
"Middle-earth: Shadow of Mordor"=C2=AB then?
