This is a small issue, but how 10.27.0 handles the Self Service Branding Header is not ideal for any company branding. Resizing the Self Service window distorts any image you have there. Not sure how this made it out of QA.
I like the new layout in general, and not having any categories makes life so much easier (facepalm, sarcasm). But yeah, our branding doesn't look so nice when the user eventually resizes the Self Service window and the image gets stretched out of it's 2.98:1 aspect ratio... Yuck!
I think I have figured out the problem. I think whoever put the specs into the template for the default macOS branding header may have made a typo.
The specs given are 335x1000
I went forward assuming that it was 2, not a 1.
My specs are now 335 x 2000
This shows my photoshop document in the background and my Self Service in the foreground, so you can see that the distortion is gone.
So I say "TYPO - It should be 2000 pixels wide, not 1000"
Curious if this is still an issue with 10.33? There's a "branding" fix listed, though it mentions "icon".
