Problem with black background of bookmarks and context menu in incognito mode

[ghost]

I am Japanese.
I am using a translation tool (DeepL) to write this text.
I'm sorry if my English is strange.

I am using ungoogled-chromium in incognito mode.
Since version 96, the background of bookmarks and context menu is black.
Black is hard to see, so I want to change them back to the same color as in version 95.
What should I do?
