Hi @meshwesh,we are here to help with all sorts of issues, so I’m happy to try and assist 🙂 Sorry to hear about your troubles.. have you already tried going through the ‘improve calibration’ option via the Tobii System Tray Icon? (available if you click your username)
It would also be worth making sure the tracker is not facing any sources of Infrared light such as an openwindow or spotlight, so worth having a look at your environement.
Have you tried calibrating with another user to see if the problem persists? Would be useful to know this as well.
