I have what seems to be the same problem, as detailed in one of my prior posts. I have provided screenshots to the Boyue Team on Facebook, and a sample PDF that I read when the issue arises, without however receiving any indication from the Boyue Team that a fix is in the works.
While using either KOreader or the Boyue reader, there is an occasional lag, followed by what I have determined is the failure to erase the current page N, before displaying page N+2 on top of it, "erasing" page N+1 which was never displayed - creating ghost images of page N+1. The problem has persisted through the 8.1 update, and all other updates, as in your case.
I have made the symptom less bothersome by being extremely careful about sending multiple or rapid page turn signals (rereading the page when there is lag, which in my case works because my reading material is impossibly difficult to understand on a first reading anyway), and whenever the corrupted display appears, hitting the power button to invoke the screensaver, and hitting it again to restore the screen. The screen usually displays the page after the one I intended, and in that case I have to tap to the previous page.
Boyue Team, if you are listening: Best wishes for a fix in the next update!

Is this well known problem with Alita/Boyue devices?
Lol also it really like to freeze randomly when flipping pages and it's driving me insane (doesn't accept any input for a while and then skips two pages at once... it doesn't depend on resolution or file size of the cbz/image). I was thinking 8.1 will make all more smooth but I guess I was partly mistaken.
