I'm running up-to-date Debian 10 + backports.

While using ordinary everyday programs, like webbrowser with video inside, text
editors, etc. my visuals suddenly froze a little while, but audio still playing
in background. 
Keyboard still worked, but screen graphics was garbled as show in the attached
picture. GPU fan speeded up and down a few times and settled again.

I managed to switch to another TTY and dump informations about crash before I
rebooted the machine.

Note that I often suspend my machine after work.
