Yes.
This is probably because the CRT hasn't warmed up yet on a cold boot. It goes from this to a normal boot screen?
very unlikely in a 512k IMO
Even though less frequent, ROM sockets on a Macintosh 512k can become corroded after nearly 40 years, which can sometimes cause vertical bars at startup. To address this, thoroughly clean the ROM socket contacts with DeoxIT contact cleaner spray and then carefully reseat the chips.
It's worth a try since it's a far more simple job than desoldering RAM chips on that motherboard.

Idk what a hot restart is but quickly shutting it off then on shows it but if i turn it off wait a second then turn it on it doesnt do the vertical bars
