strange problems ! with 5.4RC's

I have some strange problems lately. This issue came when i started to 
use 5.4RC's. For some reason after working 1-2days on my laptop without 
reboot or something else my touchpad was barly usable. The effect was 
like someone else was moving my pointer back to it;s possition like it 
was stuck on that spot. This apeared twice from PRERELEASE to RC4 
testing on my laptop, after reboot everything comes back to normal with 
no such effects.
Could this be from a window manager or X ?
Here is a dmesg from my hardware :
