I resolved it by
pi->name = strdup("Android touchscreen and stylus"); to pi->name = strdup("Android touchscreen");

https://code.qt.io/cgit/qt/qtbase.git/tree/src/plugins/platforms/xcb/qxcbconnection_xi2.cpp

} else if (nameLower.contains("waltop") && nameLower.contains("tablet")) {
    // other "Genius" tablets
    // WALTOP International Corp. Slim Tablet
    isTablet = true;
    tabletData.pointerType = QPointingDevice::PointerType::Pen;
    dbgType = "pen"_L1;

QT application on linux crashed when mouse click.

remove stylus
