--- Comment #13 from Wyrex wyrex@openmailbox.org --- I finally found a way to work around this. These two must be set and corruption goes away in Direct3D fullscreen:
MESA_GL_VERSION_OVERRIDE=3.0 MESA_GLSL_VERSION_OVERRIDE=320
Setting higher GL version causes black screen and "Mesa: User error: GL_INVALID_ENUM in glGetString(GL_EXTENSIONS)". Higher GLSL version causes corruption.
