I swear I have a sixth sense...
I said to myself "I wonder when viper is gonna be updated?" and lo, less than 2 hours ago a gift in the form of an update has been left in the repository.
Gonna flash right now.
Thanks @sandy108

New version seems stable, but laggy compared to previous.
Slow to the scroll/typing, without any other changes from my side, besides clearing dalvik/cache after flashing

Disregard this.
I made a clean install, after managing to encrypt my /data flashing the wrong vendor, and everything is smooth again.
I think I am "stuck" with viper for almost a year now, the most stable and reliable rom for F1 I have tried.

Give it a try guys.
