IME buffer texts blur on commit input

[t7yang]

Type: Bug

1. install Dark Lavender theme (this theme created by me).
2. open any git project.
3. start typing on the commit input using CJK IME.
4. the buffer texts are blur.

• this issue only occurs on "Dark Lavender", the built-in theme is fine.
• the issue only occurs on commit input, I tested on other inputs like global search input and extension search input, everything works fine.

as the theme creator, I can only provide UI and token colors, I don't know why only my theme has this issue and only happens on the commit input.
