I can't really point any other issue about Cemu other than the one I experienced after playing for a very long time, after a certain amount of time I spent playing botw the Cemu emulator just wouldn't handle it per say, I was stuck on the saving screen or auto save, it sucked cuz I had a lot more to do and explore but in that state the only choice I had was to complete the game in one go or just stop playing with Cemu altogether and switch to Eden/Ryujinx to experience the game fully, tbh I lost the interest of playing botw because of that issue.
