Hi @wodz82,
Unfortunately it looks like we can’t reproduce this issue on our side.
My assomption is that you might have uploaded your profile picture before activating the theme, in which case the image will be scaled down to a smaller size than intended.
To fix that, all you need to do is to go to your profile and re-upload your profile picture, then the image size should be good.
Please let me know if it worked.
Best regards,
