logo on pdf invoice is blurry

Hi, what could be causing the logo to look blurry on the pdf invoices?

I have the latest self-hosted version of invoice ninja installed.
Clean design layout.

using .png logo 400x100px
I’ve tried larger dimensions and different file ratios, but it still shows blurry on the pdf invoices.

Also my logo isn’t showing up in emails. Doesn’t show in the email template preview either

Hmm… it’s possible the two issues are related, maybe try with a different format image?
