After some investigation, it turns out that if i run the “simpleGazeSelection” demo, the pink dots are also shifted compare to the gazeTrace. If i have my two screens it is shifted to the right, if i have only one screen it is shifted to the left ( A LOT shifted, you can see in the picture: https://ibb.co/cqkeRQ ) ..
I must inform that everything work fine out of unity ( if i test calibration it is fine ) I tried to recalibrate each time i change screen configuration but it didnt resolve the issue. I also tried to set the DPI to 100% as suggested here :
but it also didn’t solve the problem .
