I find left hamburger menu (at right to effect gallery button) in kamoso does not work. I find another QT application "QT V4L2 video capture utility" work (image is show) with intel driver, xorg session. Effect gallery in kamoso does not work.
terminal output at the moment of crash: $ kamoso No device found qrc:/qml/Mode.qml:5:28: Invalid property assignment: string expected - Assigning null to incompatible properties in QML is deprecated.
