THe support for InputMethod is done a bit by hand right now, because the 
workarea of LyX is completely built by ourselves. I do not have any idea 
of the culprits of Chinese editing.

What version of LyX is that, by the way?

I would be taker of help in this department, even concerning the set up 
of things like ibus for keyboard switching. We have issues with that in 
LyX 2.4.0dev.

Best regards,
