something strange is happening in the system with the .tex icon

I enjoy using the terminal and I use different and varied software. But a recurrent, omnipresent and strange issue is the rendering of the .tex icons. Any clue for what’s happening?

The Yazi en wezterm seems fine but I don’t know what’s wrong then in vim stratify (also on vim yatline I have the exact same issue). Any clue would be appreciated. Also any specs question would be happily answered.
