I've just replaced the M.2. drive in my Win Max and everything appeared to be OK at first until the touchscreen began acting strangely.
It registers presses but where ever I press on the screen, it registers the press on a different part of the screen.
It's almost as if the screen is reversed horizontally and vertically.
I have tried re-installing the driver, fresh install of Windows, cleaning the screen, calibrating the screen and a different driver to no avail.
It's like the firmware for the screen has corrupted.
GPD has no firmware tool for the screen or the device itself so I cannot check if this is the case.
I tried to boot into Ubuntu to see if it happened on there but the OS didn't recognize the screen correctly.
Any thoughts from anyone?
