Screen flickers with Linux 4.6

[Poulad <poulad.pld@gmail.com>]

Hi
   This is Poulad. I use Debian Jessie and the testing repo. About 20 hours ago I upgraded my installed packages and rebooted the system. I see in the newer version of kernel, when the Xorg service starts the screen flickers. I've tested it on KDE and LXDE and the resutl is the same. For now I am choosing the 4.5 version of kernel in GRUB which runs OK. Please let me know if you needed more information about it to track the problem.

During upgrade, the following packages were installed:
(/var/log/apt/history.log) :
Install: linux-headers-4.6.0-1-common:amd64 (4.6.1-1, automatic), linux-headers-4.6.0-1-amd64:amd64 (4.6.1-1, automatic), linux-kbuild-4.6:amd64 (4.6.1-1, automatic), linux-image-4.6.0-1-amd64:amd64 (4.6.1-1, automatic)

Thank you
