In https://lists.debian.org/debian-user/2017/05/msg00781.html I explained how,
but he hasn't written here whether he tried or not. I asked for another
Xorg.0.log, in order to find that out (among other things), but that hasn't
happened.
If the Intel driver has already been tried, then his focus probably needs to be
shifted to hunting down anything to be tried that's specific to his Braswell
chipset generation.
One possible thing to try (which AFAICT can't work in Gnome), is disabling of
compositing. Whether Mate can work with compositing disabled I have no idea, but
I know it can in Plasma and TDE, and most likely also in IceWM, LXDE and other
lightweights. I do it, when necessary, or desirable, globally, via
/etc/X11/xorg.conf.d/70-extensions.conf:
Section "Extensions"
Option "Composite" "Disable"
EndSection
