Thank you for the quick response, Chris!
I still don't understand why an X server restart is not enough to make it work again?
What does "intel_do_flush_locked failed: Input/output error" mean?
Is it just a fact of life these days that userspace can mess up the GPU to a state where only a reboot helps?

It starts as a userspace hang that takes out the GPU. Update mesa to
one of the 19.x stable releases.

File a regression report against debian, X should not crash and did not
use to crash over a mere terminal GPU hang.
