So, I should probably report this bug to Ferral Interactive (studio responsible for the Linux port), right? > You could force-enable it by setting force_glsl_extensions_warn=1 and > MESA_EXTENSION_OVERRIDE=GL_ARB_arrays_of_arrays ... I think. The correct override is: # force_glsl_extensions_warn=true MESA_EXTENSION_OVERRIDE=GL_ARB_arrays_of_arrays Setting force_glsl_extension_warn=1 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 »[radeonsi] Implement GL_ARB_arrays_of_arrays for "Middle-earth: Shadow of Mordor"« then?
