Hi @rishikapadia7, thank you four your detailed report and sorry to hear about your issues.
So it seems that things are working as expected on the Thinkpad but any time you revert the eye tracker back Surface Book, the same issue returns.. and vice versa?
I am afraid that we cannot divulge details regarding the algorithms but it’s certainly a rather unusual issue you have discovered for which this is the first time it has been reported. Perhaps another user viewing this point might have seen it before.
In the meantime, I will pass along your information to the developers to see what advise we can give. May I ask if there was in fact any *environmental* difference between the two laptops? ie different rooms ,lighting conditions, etc.?
