--- Comment #7 from Alexander Jones (acjones8@hawaii.edu) ---
I can also confirm this bug, I'm suffering the exact same problem with my
ThinkPad A275. My glitchy screen looks like this: https://imgur.com/tKAxlI7

I'm also not able to restart X or switch VT, but I can confirm that the user
applications still run, as I've heard Kmail issue a notification while the
screen was glitchy. Other functions of the laptop, like the fan speed and
keyboard illumination, still work perfectly after waking up and function like
normal (if I press the shortcut to light the keyboard up, it changes intensity
properly). Switching back to an older version of the kernel, 5.4.10 in my case,
fixes the problem as well.

Curiously enough, I checked my dmesg for the SAD message after suspending with
the older kernel, and it now reads this:

[    5.450379] [drm] SADs count is: -2, don't need to read it

So it seems to be related to reading whatever the SAD is.
