Unlikely a bug report for a product as old as Jessie would get fixed.
Versions have advanced considerably since. It may have been a bug that is
long since fixed.

Lspci doesn't report the kernel driver or the DDX (X driver dependent on
the kernel's modesetting functionality, KMS).

You may find switching DDX would clear up the problem. In Jessie the
Intel DDX is in xserver-xorg-video-intel, while the modesetting DDX is
in xserver-xorg-video-modesetting. Switching can be as simple as
purging one and/or installing the other.
I have the same GPU but no OS so old, and have seen no evidence of the
corruption you describe using the modesetting DDX:
