Arial Bold  Suggérée par fmontpetit 

This is the strangest "Arial Bold" I've ever seen

I'm not saying it's a match (well actually I WAS saying that before...). But it's not "strange".

size matters, especially here I'd say that this screenshot is from video file, maybe video compression screwed the ol' and well known Arial?

I know you mean that I shouldn't green these: it's too hard to see and be 100% sure. I will try to be more careful.

Could be Arial still, but only from supposition (unless we have better screenshot)
