Trackpad Ghost touches after some time. Poweroff is workaround.

I had a similar issue, with some discussion here:

https://forum.pine64.org/showthread.php?tid=9856

Although it's with a very different configuration than yours.

Yes it is the same issue as I read your discussion.
I tried really a lot configuration with/without synaptics etc.
I think it is a hw issue. With new manjaro, sleep mode also help me so it is quick fix.
After I received 3rd LCD with problem and now this . 
Thx for response. I will follow your thread if anyone find solution.

EDIT:

I was thinking about reseting keyboard by usb bus to fix this.
I tried 

Code:

lsusb
Bus 003 Device 002: ID 258a:001e HAILUCK CO.,LTD USB KEYBOARD
sudo usbreset /dev/bus/usb/003/002

after that keyboard is OK, but trackpad is total weird and need restart PBP.
Can you try it? I will try also go back to older firmware not from community.
