Does this happen for every language and every time?

I cannot reproduce this with lua_ls.

On top of that, your repro config contains variables such as keymappings that I have no clue what it is. Please give us a reproducible config!!!

yeh! in my case, it happened in clangd\pyright\lua_ls most each time. And I find that follow_cursor=true cause this error. here is my keymappings:
