after severals hours of googling my issue, i don't have other choice than asking you
.I'm facing an issue with my rpi3 and raspbian that i don't have if i user ubuntu Mate for example.
I've got a usb touch screen and when i click on a part of the screen (on desktop for example )
I click on the left side that's ok and when i make a second click wherever it make something like if i was selecting an area of the desktop (cf pic)

and of course it make the calibration wrong...
However this problem does not occurs on Ubuntu Mate where the touch is perfectly working.
Does anyone has this issue?
Thanks all ;
