YES flexbox could cause performance problems and make your application slower, specially if it's used too much and in the wrong way or for wrong purposes, for example consider you have a page that has a lot of elements in it, using flexbox for ordering all of them and setting each element in their place using flexbox is a horrible horrible thing to do, the reason is that for any element in the page that has flexbox properties applied to it the browser has to make some calculations for width, height, distance from another elements and the parent window and etc.(for such scenario using grid is the best option). having too many of flexbox elements can cause calculation overloads thus performance issues, and slower application.
I recommend this article, it explains where it shouldn't be used and why
