I noticed that this line: <header style=”width: 1903px; position: fixed; top: 32px;” id=”masthead” class=”site-header” role=”banner”> when does not have a width specified does not jitter. So if i remove the style and make that line equate to <header style=”position: fixed; top: 32px;” id=”masthead” class=”site-header” role=”banner”> and scroll up, the sticky menu hides smoothly. Then once I start scrolling it jitters (invoking and revoking it).
Thanks for giving Ultra a try, the feedback is most welcome.
There is a substantial update pending approval. It’s about half way up the WordPress.org theme update queue right now but being Easter it might take a bit longer than usual to get checked and hopefully approved. I hope the problem you’ve raised has been resolved.
I’d rather you didn’t install the update on your main WordPress installation until it’s been approved. Do you perhaps have a local version or test site somewhere you could test it on? If so, I’ll send through the ZIP. If not, I’ll setup a testing instance.
