I want to cancel the display effect in vim, but I don't know which plug-in causes this automatic highlighting?

Question

See the screenshot, in which printf, hendry, ssid are surrounded and displayed with an orange background. Currently, I want to cancel this display effect. My vim plugin uses spf13.

Answer 1

Looks a bit like search highlight。
运行命令:nohLet’s try it.

Answer 2

It’s because the spell check is turned on.
Type :set nospell in vim to solve the problem.

I will only turn on this option when writing documents in the future; usually, for example, when writing code, it is turned off by default.
