I've seen similar problems also with Debian Stretch (not Jessie) and was able
to fix it by disabling SNA (default) with UXA (old) Acceleration.
This was with a Mobile Broadwell.

Cloud you try this...

Create a file say 20-intel.conf and put in /usr/share/X11/xorg.conf.d directory
in Debian Stretch:

Section "Device"
    Identifier "intel"
    Driver     "intel"
    Option     "AccelMethod" "uxa"
EndSection

Restart your DisplayManager and try to reproduce.
