Default [Q] Touchscreen issue when charging sony sola cm11

Hi,
I have a sola with the latest cyanogenmod 11 (03.04.2014) + gapps.
When I plug in the charger the touch driver goes wrong. If I try to do anything it's always feel my finger everywhere and open, modify everything.
Sometimes I turned on the wifi, satnav, flashlight from the lock screen what was weird.
I tried to wipe the cache, dalvik cache, factory reset and format system folder and still the same problem...
When I'm charging it's just useless.
