However, it is rather problematic, because if you parse the hid-recording[1], we receive: 14.845206 ReportID: 3 / Confidence: 1 | Tip Switch: 0 | Contact Id: 0 | # | X: 627 | Y: 364 | ... | Contact Count: 1 | B1: 0 | # 16.526414 ReportID: 3 / Confidence: 1 | Tip Switch: 1 | Contact Id: 0 | # | X: 0 | Y: 306 | ... | Contact Count: 1 | B1: 0 | # 56.993181 ReportID: 3 / Confidence: 1 | Tip Switch: 1 | Contact Id: 0 | # | X: 681 | Y: 316 | ... | Contact Count: 1 | B1: 0 | # Which matches the evemu-record (finger up at 14.845206, then down in (0, 306), wait 40 seconds, and move to (681, 316)). So this means that it is either a firmware problem of the touchpad, or a I2C error. Do you have any errors/warnings in your dmesg when this error occurs? I am not sure it is a firmware issue because PS/2 works, and the PS/2 binding should be using the same raw data than the I2C binding. You might have more luck with a 4.5-rc4. Meanwhile, I'll try to talk to the synaptics engineers about the issue.
