    So I use my 2016 Razer Blade with the Synaptics driver and installed the precision drivers.

    I am having some annoying issue so I just wanted to address about this issue. Here is some background.

    The 2016 Razer Blade shipped with the Synaptics Driver out of the box, and it had this issue: where the cursor will skip back to its normal position when it was quickly moved by a short distance.

    This issue was confirmed to be a palm rejection issue where it was programmed to move the cursor back to its normal position when it happened to move a slight bit by your palm when typing.

    However this kinda rendered it unusable and people upgraded their drivers to the which was much better in every aspect. The bug shown in the video wasn't present anymore, however it was lacking very precise movement and the palm rejection wasn't as great.

    Recently there was a hack where you could install precision drivers onto your synaptics touchpad. Some users were reporting that they were having an issue where the touchpad stopped working after waking up from sleep.

    The solution to this issue was to downgrade the synaptics driver. So basically if you installed the precision drivers over the synaptics drivers v., you got this unresponsive issue. If you uninstalled the synaptics drivers, installed the older and installed the precision drivers over that, the wake from sleep issue was resolved.

    So I am using my touchpad with precision drivers on top of the synaptics which seems like the standard these days.

    However I am having a slightly annoying issue. Sometimes when I am moving short distances, the cursor skipping back bug will trigger for some reason. I wan't able to replicate this consistently like I did on the video, but it is definitely there.

    Now I am wondering if this skipping issue is caused by the older drivers lying beneath the precision drivers. I wonder if there is another version of the synaptics drivers that might fix this.

    I don't know if this skipping issue is purely due to the precision drivers, or due to the synaptics drivers lying beneath the precision drivers.

    Has anybody been experiencing this issue / or found a workaround?

    I haven´t been able to reproduce the issue when using the precision driver over the synaptics 19.2. Do you have the SynTPenh Caller Service disabled in Services?

    Just recheck it since I’m using mostly mouse and didn’t have such issues on 19.2 driver with precision hybrid feel great like MacBook touchpad to me.
