I had this same issue and the 4K fix didn't work as I don't actually have a 4k monitor. For others with this issue, I fixed it by remembering a couple hiccups in other games I have had that required a driver rollback, which I kept putting off because I couldn't be bothered to do it until I absolutely had to today for POE2. Geforce driver 397.31 is pretty unstable on many of the 10XX line of cards. Rolling back to 391.35 fixed this issue for me. Although using DDU in my case, i had to run it once, and then again to clear the Geforce cache and re-run it again to finish cleaning up the old driver in desktop mode because I ran into issues with getting safemode working.
