I used to see this quite frequently with my Debian install (Daniel
Thompson's installer[1] and kernel[2]) To me it looks like the video
readout is misconfigured and the framebuffer is smeared vertically, so
the lines you see are the logo and boot spinner.

Certainly sounds like it. Like Eduardo, I worked around by forcing the
system off and then booting from that state.
I only recently installed fedora 34 and I haven't seen the horizontal
lines, but I also have trouble rebooting. The screen blanks, but the
machine seems to hang instead of rebooting, and I have to force it off
by holding down the power key for 5-10 seconds.
Cheers,
