Hi, I have an embedded linux device with AM335x CPU on which I am running QML applications using the eglfs platform. The Qt library version is 5.1. For the input I have a touch panel with usb egalax controller that is used by the evdevtouch plugin. Input works, but the problem is in performance. Only slow movements are followed - on faster movements the position is updated only on stop.
This behaviour can be seen even by simple QML app that writes the coordinates on the screen. I have no problem if I use the mouse. If I run the "ts_test" from tslib the touch screen works fine, so I guess the reason is not in the driver. Has anyone experienced a similar issue or has a clue what can be done?
