Font blurry when zoom in/out

[Moatez]

Hello , 

I am trying to fix font blurry issue with my custom visual when zooming in or out .

Example :

140% zoom ( not blurry )

150% zoom blurry 

This is barrely visiable in this case but if the text is smaller its really anoying 

Any help is really apprciated 

Thank you !
