Remover efeito no menu de navegação

Qual é minha questão:


Gostaria que fosse removido este efeito que aparece  em torno do link, pois ele está causando bug quando se passa  rápido demais sobre eles.

E que permanecesse apenas o efeito de aumentar a fonte quando o mouse está sobre o link.

Segue o CSS

Código:
