The header would look nicer if it had a high-resolution logo. I would do it myself but I don't know how to locate the source file for the banner. It can be a 2x png or a SVG file.
Created attachment 133443 [details] Trying to learn which element that is It's this, actually: https://krita.org/wp-content/themes/krita-org-theme/images/krita-logo.png And I agree it looks low-resolution on my 4k screen.
I just update the logo. It is 2x the size with what it was before.
