I used this version of Remix OS: https://forum.xda-developers.com/remix/remix-os/remix-os-pc-hacked-edition-ota-v2-0-201-t3345968.

The way I remember it, I downloaded QooApp right after the first RemixOS boot, downloaded FGO, then unrooted the OS. Works clean as a whistle, though minor memory leaks happened sometimes. You don't really need to update SuperSU binary to unroot it, if I remember it correctly.

The unrooting process does take quite a long time depending on your PC, but it's worth it. Fair warning though; with the discontinued support for Remix OS, any problems on the OS that happens after this won't be fixed.
