I don't see Bay Trail on https://en.wikipedia.org/wiki/List_of_Intel_chipsets 
which likely means your laptop's construction design predates Jessie's 
original release a year ago. Maybe Stretch has support for it? Maybe 
switching between modesetting and intel X driver is what you need, depending 
on which is in use now. /var/log/Xorg.0.log will say which video driver is in 
use. If it's not intel or modesetting, X is running on an inferior fallback 
driver.

https://www.reddit.com/r/archlinux/comments/4cojj9/it_is_probably_time_to_ditch_xf86videointel/ 
could provide some insight on driver selection, but you still may need Xorg 
or video driver or both from unstable.
