Symfony loading assets on every page change

  assets, fonts, less, symfony, webpack

I am using symfony 4 and webpack encore and on every page change or reload my assets are loading what results in content jumping and white flash of body background white. My custom font is loading everytime too. What am i missing or doing wrong? I dont have checked "Disable cache" in developer tools. Can it be the symfony dev server or do i need production build of assets?

Thank you for any help.
