CPU platform : i.mx6 Quad

Linux kernel : 4.1.15

Qt : 5.8.0

filesystem : xwayland

When touch calibration is performed through the weston-calibrator, it operates normally in a wayland type (parameter : -platform wayland) application. However, when running in x11 type(parameter : export DISPLAY=:0) touch only works when fullsize. The application was created in Qt 5.8.0. When it is not fullsize, normal operation will only be performed with the fullsize option in Qt without normal operation even if the touch is performed using the maximize button.  Could you tell me how to solve it?
