Priority: P2: Important
Affects Version/s: 5.5.0, 5.5.1
Fix Version/s: 5.6.0 RC
Component/s: GUI: Basic Input System (keyboard, mouse, touch)
Environment:Reported on Arch Linux, Debian and Gentoo with Qt 5.5.0, 5.5.1.
As of Qt 5.5.0, plugging in or unplugging an input device with a Qt application running prevents the awesome window manager from receiving mouse input events. Other applications continue to work as expected.
For non-root windows, this was fixed by setting the appropriate XCB event mask. However, the fix does not seem to be applicable for the root window.
Setting QT_XCB_NO_XI2_MOUSE=1 works around the problem.
