SHR-Core : Display issue?

I seem to remember something about event filtering being moved from 
kernelspace to userspace.  If that is correct, you are running without 
any event filtering.  The signal from the touchscreen hardware is very 
noisy, and software is needed to average it out.

Upgrading the rootfs might be a good idea anyway.  I have the last shr 
unstable installed in NAND on my freerunner, and the latest shr-core 
installed on an sd card.  SHR-core is stabilizing quickly and I use it 
as my daily phone now.  If you have everything working the way you want 
it with shr-unstable it might be worth making a backup.

Last winter I wrote myself a script to go from a fresh install to 
customized.  It installs programs, adds extra kernel modules for some 
sensors I added, changes some config files, and downloads then extracts 
a backup of my home directory.  This makes it a lot less daunting to do 
a reflash.
