Hi @horsky, most unusual indeed! thanks for the extra information.. I will report to the developers to see what they see.. I assume you are running the latest Tobii Core Software? How about power option for the eye tracker in device manager? I can imagine how this might be quite an annoyance so we will try to find a good solution for you.
If you disable the Tobii Tracking Windows Service (start -> run -> services.msc) the problem persists?
Yes, the eyes are X’s when nothing found, it’s normal behaviour. Best wishes.
