I have an Acer Aspire VN7-791G. I am using the latest Windows 10 version (1909 18363.720), and keeping it up to date. But my touchpad stops working randomly and this freezes my computer for 1-2 sec.
Also, when I look in Device Manager, it keeps refreshing. Sometimes the Synaptics section is hiding, and then it shows again. It is not related to cables or other physical issue, because I tried testing in Ubuntu and the touchpad works well.
