"Snow" screen glitch on Pixel 7 running GrapheneOS

My phone started malfunctioning the other day, where the screen suddenly displays "snow"/white noise instead of a proper image. Sometimes it seems to fix itself for a while, but then does it again, which makes me think it might be software rather than hardware.

While researching the problem, I ran across this article showing the same issue on Pixel 10s, and concurring with my guess that it might be a software thing.

(My phone screen looks just like that, except tinted blue instead of pink.)

But mine is a different model, running non-stock firmware. Is this also a known issue on Pixel 7s and/or phones running GrapheneOS, or is it specific to the Pixel 10 and stock firmware? Has progress been made on diagnosing or fixing it since last September when the article was written?
