It was the kernel from Debian/unstable at the time I reported the
bug, and it still occurred with linux-image-5.4.0-3-amd64 5.4.13-1.

So it seems that this is not sufficient for me.

Note that in my case, the screen does not remain off (on my laptop,
backlight gets visible) but it is black. Moreover, this is not after
resume, but after locking while the machine is still running. IIRC,
I have not noticed any issue after resume on my laptop.
