I have a sticky header with a transparent background and white text that changes to a white background with black text when scrolling. This works perfectly for navigation elements with no submenu. The elements with submenu disappear when scrolling – obviously this becomes white text on white background. These are my settings for the sticky header.
I guess this error is related to the one I reported (WIP: Nav - Scrolling Text color is not applied to Items with subitems!).
The color issue is solved, but unfortunately you forgot to apply this fix for the transition. I have a transition on my elements, but the transition is not applied to elements with subelements.
Could you have a look?
