Comment 6 for bug 1427182

Despite changing etc/X11/Xsession.d/99mate-environment to set QT_ACCESSIBILITY=1 only when starting the mate session, you still have etc/profile.d/qt-accessibility.sh which always sets it.

I personally think accessibility support should always be enabled if it's a switch that doesn't change behavior for all users and just makes the use of accessibility features easier (orca, etc.), but is this on purpose?

What change in behavior do you need QT_ACCESSIBILITY to be set for?
