I have a PBIX report with 15 report pages in it. 14 of those pages are hidden and I have one main menu page with bookmark buttons setup to navigate the user to the different report pages. I have a Page Background image (JPG) on the main menu page. Navigation from the main menu buttons to the respective reports pages has been smooth and seamless up until a few days ago.
In the last few days I have started experiencing a jittery transition from the main menu to the report page as the visuals on the page load. The page background image partially displays for a fraction of time as the report page is loading, slightly longer for pages with high complexity embedded in it.
Wondering if there has been a change to how the report pages load in the browser? This is quite distracting for the user experience and suggests there is a performance issue with the report itself, however this was not the case a week ago.
