For the records, Mesa reports GL 3.0 in compatibility profile.
It reports GL 3.0, except with lots of other extensions available too (e.g. ARB_sync). Otherwise WoW's OpenGL mode would still crash despite my setting MESA_GL_VERSION_OVERRIDE=3.3COMPAT.
But not ARB_viewport_array, which is the likely reason for this bug report.
