Windows 10: Ghost keypresses sent on tablet

When using my tablet (a slate, cube mix plus) sometimes ghost 'keys' are magically held down.

For example perhaps the 'control' key becomes stuck down. Except I didn't press the key, I don't even have a keyboard, and I didn't even have the touch keyboard open.

Opening the touch keyboard and pressing the corresponding key doesn't unstick it. Attaching a usb or bluetooth keyboard and pressing the key doesn't unstick it either.

This has happened to many keys; ctrl, alt, shift, win, and sometimes character keys too like x. This can happen with any program open, sometimes explorer, sometimes chrome, sometimes mspaint, etc.

I suspected it was to do with the GPIO keyboard dock (the same as you would find on a MS surface), but I taped over the port and still have the issue. No one knew how or even if it's possible to disable the dock in device manager, so I haven't.

Any help would be welcome. Obviously this is not a fun bug. If you have a document open it may exit without warning, or leave you unable to save. Often you can't open the touch keyboard, or start menu. The only fix is a hard shutdown with the power button. I think with the right program I might be able to see what process or device is sending the keypresses.

Thanks in advance.

Firmware update - whats new?

Sometimes this can happen if the keypress volume is on. Try going to profiles and setting the keypress volume to 0.
