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.
