Hey @vlntnt,
Please provide the browser your using and its version. If you’re not sure, please visit https://supportally.com/ and give us the OS and Browser details. This is so we could replicate the scaling (stretching) behavior and maybe we can provide some guidance on how to prevent that.
On my end, tested in Chrome, IE, Edge and Firefox browsers, the logo’s not scaled too.

Also make sure your browser’s not zoomed in because it will scale the elements up including the image. That’s the time it will be blurry and it’s not because of our theme. Compare the images below. One is crisp at 100% zoom and one is blurry at 110% zoom.


Thanks.
