M720: mouse freezes, but no gestures

[ruilya]

I've modified the example configuration:

devices: (
{
    name: "M720 Triathlon Multi-Device Mouse";
    buttons: (
        // gesture key
        {
            cid: 0xd0; 
            action =
           {
                type: "Gestures";
                gestures: (
                    {
                        direction: "Up";
                        mode: "OnRelease";
                        action =
                        {
                            type: "Keypress";
                            keys: ["KEY_UP"];
                        };
                    },
                    {
                        direction: "Down";
                        mode: "OnRelease";
                        action =
                        {
                            type: "Keypress";
                            keys: ["KEY_DOWN"];
                        };
                    },
                    {
                        direction: "Left";
                        mode: "OnRelease";
                        action =
                        {
                            type: "CycleDPI";
                            dpis: [400, 600, 800, 1000, 1200, 1400, 1600];
                        };
                    },
                    {
                        direction: "Right";
                        mode: "OnRelease";
                        action =
                        {
                            type = "ToggleSmartshift";
                        }
                    },
                    {
                        direction: "None"
                        mode: "NoPress"
                    }
                );
            }; 
        }

    );
    hiresscroll:
    {
        hires: true;
        invert: false;
        target: false;
    };
}
);

Here's the output of sudo logid --verbose debug:

Using xev to test the config, I press the thumb button, cursor freezes, moving mouse does not produce any events in xev output.
