I'm working on a touch driver for a 2.8in display. Driver seems to be working fine for single click, long press etc, but when I i.e. want to move an icon on the desktop I will end up with the 'shadow of the icon' on top of my pointer.
I've added an evtest output of such action. Any idea what is causing this and how to debug?
