Flux disable himself for few second after sleep mode w7

[0zmox]

Hello,

I'm using Flux for few years without any trouble.
But recently I Factory restore my laptop and flux doesn't work as it us to do.

Some times, but I particulary notice when my computer leave sleep mode, my screen flickering between "normal" and "flux" mode

I search on internet same issue but coul not find anything. I saw it could be cause by conflict between software.
I try disable Nvidia - Same issue
I search with msconfig other programe that could cause conflit but don't find anything
