Apparently, this is not solved due to switching to UXA, but because UXA
also reverts to DRI2.
SNA does work without issues, as long as it's combined with DRI2 and the
xserver-xorg-video-intel driver.
So this configuration works as well, and is probably preferable:
I can confirm the issue of graphical glitches, being on a fully up to
date version of Stretch with Linux 4.9, Gnome 3.22, Mesa 13.0.6.
I'm testing this on a Thinkpad T400.
Kind regards,
Nico Rikken
Other things I've tested that didn't help:
Updated the following packages to the versions in experimental:
- libegl1-mesa 17.0.3-1
- libgbm1 17.0.3-1
- libgl1-mesa-dri 17.0.3-1
- libgl1-mesa-glx 17.0.3-1

I have a couple of GM45 ThinkPads and G41 desktops running Debian stretch with
the GNOME 3.22 desktop.
Quite regularly, the screen glitches / distorts, followed by this line in
dmesg:
