Onigiri: Fixed position title/logo image reversed in large screens

Hello,

I have unchecked the box “Fixed position title/logo image” and on laptops the logo image stays on top when I scroll, but on larger screens like iMac the logo “follows” while I scroll and ultimately covers part of the page – making it difficult to read.

Is there any way I can arrange this properly, so that the look and feel is the same across screen dimensions?

Thanks, and I hope I explained the issue well enough.
