I'll check again, then. I have checked with a vanilla reinstall of Debian 9, using the Mate desktop, and Qt 5.7.1. When QT_LINUX_ACCESSIBILITY_ALWAYS_ON is not set, I don't see Qt applications in accerciser, only the Mate applications. If I set QT_LINUX_ACCESSIBILITY_ALWAYS_ON, I do see them. On my current desktop, I have Qt 5.9.1, I made quick tests, it seems it behaves as I expect, so perhaps we can indeed avoid setting QT_LINUX_ACCESSIBILITY_ALWAYS_ON now. I'll retest with a vanilla reinstall of debian testing, to be sure. Samuel
