That would be my code. The environment is only modified if
QT_XCB_FORCE_SOFTWARE_OPENGL is set, a workaround for old OpenGL-1.x-only
drivers. I simply do not know a better way to force Mesa's libGL to use
software rendering in Qt applications without making it global for all
applications.
There is no environment changing (and thus no race) in the common case where
the workaround environment variable QT_XCB_FORCE_SOFTWARE_OPENGL is not set.
