    <thetext>If I view [this page][1], the page is blank.  If I move my mouse around on it, elements bits and pieces of the elements appear.

It started happening for me macOS 13.01, but is still present in 13.1.  I notice that Mozilla and Chrome are fine, but [Orion][2] has the same bug.  WebKit seems to be the common thing between Safari and Orion, but I haven&apos;t found any issues listed anywhere, for Safari, Orion, or WebKit.

Another weird fact is that, as soon as I focus on another window, all of the elements on the page render entirely, but as soon as I focus back on the page, they a disappear.

**Update**

I&apos;m using a Studio Display and the issue seems to be there when Safari is using the entirety of the Studio Display.  As soon as I shrink the browser down to fit on the 16 inch display of my MacBook, it goes away.  When I move that shrunken version over to the Studio Display, the issue isn&apos;t there.  When I expand the width of the browser to fit the width of the Studio Display, the issue isn&apos;t there.  When I expand the height of the browser to fit the height of the Studio Display, the issue occurs.

    <thetext>This is caused by the CSS drop-shadow filter. There&apos;s a max buffer size for filter input.</thetext>
