[Bug 41711] World of Warcraft - Legion renders into "sub-windows" incorrectly with DirectX/Mesa

--- Comment #18 from Chris Rankin  ---
Whatever this bug is, it requires Mesa also to support OpenGL >= 4. Which means
that WoW will work correctly provided I set the following environment
variables:

MESA_GL_VERSION_OVERRIDE=3.3COMPAT
MESA_GLSL_VERSION_OVERRIDE=420

(This is for my Radeon R7 360, which supports OpenGL 4.5 with the latest Mesa.)

WoW only really requires OpenGL 3.3, although I think some of its shaders
demand GLSL 4.2 support. So "under advertising" OpenGL support is a
work-around.
