Need help ! Weird resolution bug resulting in bad fonts and UI

Hey guys !

I recently made a new proper installation of my WoW client with the client of a friend because i've some crashes with my old mine. But now, i can't stick my new client at a good resolution i think. Here is some screens :

First, with my old client and second with my new client (look at focus plate and skada):

I've copied and pasted the WTF folder with the config sheet and Elvui folders of my old clients to my new one, so i don't think they are the issue.
Resolution are both in 1920*1080(Wide) and i already try to change them, restart the game, the computer, ...

Did you guys have a clue about what is happening ? Can you help me please ?

Best regards,

Crayven
