I've a problem with my Touchscreen 5" from Waveshare (hdmi lcd G 800x480)
The touchscreen has been recognized on the first config without calibrating or something other stuffs.
I can't touch the borders with the stylus. can't use the menu on up-right, can't use the bottom bar.
To try, i've installed TSLIB to calibrate the touch.
The calibration was success, but same problem is on, can't touch the border.
If i touch a corner, the pointer is 5 millimeters out, and if i touch the middle of the screen, it's ok.
If i do a "drag and drop", the pointer still have delay and don't go on the corners, and stay 5 millimeters out.
I've tryed the fonction ts_test and i can go everywhere on the screen, and the pointer go on the corners too.
I don't understand why on test, it works fine, and when i'm on the GUI can't use all the layout.
someone have an idea about that?
thanks a lot
